This means that the content of halogen should not exceed certain limits that are set as per the restrictions.

These levels are normally in parts per million.

Halogen-free material in printed circuit boards has features such as low wrap resistance, flame retardancy, and more thermal stability.

Printed circuit boards have a high tendency of catching fire but if the halogen-free material is used in the fabrication of printed circuit boards there are chances of combustion.

Improper disposal of halogen-containing materials has negative effects on the ecosystem hence the recommendation of halogen-free material.

What Are The Benefits Of Using Halogen Free Material For Printed Circuit Board?

Ideally, halogen-free materials contain 900 parts per million of some oh halogen elements such as chlorine and bromine.

The rest of the halogens elements levels in the printed circuit board should be 1500 parts per million.

Over the years there has been a complete transition in the fabrication of printed circuit boards from halogen-containing material to halogen-free material.

The use of halogen-free material on printed circuit boards has a wide variety of benefits. These benefits include:

  • Halogen-free materials comply with the green regulation compliance.

This makes it possible for printed circuit boards made of halogen-free material to easily penetrate the market.

  • Halogen-free material provides better insulation on printed circuit boards.

Halogen-free materials have a better insulating factor which distinguishes fire when the insulator resin comes into contact with are.

This feature makes halogen-free material suitable for printed circuit board fabrication which you will commonly find in, electronics, power products, and displays.

  • Halogen-free material provides better high-frequency performance on printed circuit boards. You can opt for a halogen-free printed circuit board that offers relatively low cost with huge frequency applications.

There is no release of any toxic gas even when the printed circuit board heats up.

Which Type Of Halogen Free Materials Do You Use For Printed Circuit Board Fabrication?

The type of materials you use during the fabrication of the printed circuit board determines the overall performance of the printed circuit board.

For instance, thermal stability, dielectric constant, moisture permissivity among other features are very vital.

Below are types of halogen-free material used during printed circuit board fabrication. They include;

  • FR4: This is the most common material for fabricating printed circuit boards in the market today.

FR4 is a halogen-free material which means it provides flame retardancy on the printed circuit board.

FR4 material has both good mechanical, electrical, and thermal properties.

FR4 provides ease of drilling and metallization during the fabrication of halogen-free printed circuit boards.

Flame retardant(FR4) provides;

  • Moisture resistance

While halogen contains material contain chlorine, bromine, fluorine, and iodine elements,

There is a certain level that the halogen-free material should adhere to be considered halogen-free.

The levels of chlorine and bromine should be 900 parts per million while the rest elements should be 1500 parts per million.

With this level, the halogen-free material passes all the restrictions making it suitable for printed circuit board fabrication.

For halogen-containing material, there is no restriction on the levels of halogen content that should be present even during the fabrication of printed circuit board.

Halogen-free materials do are very eco-friendly as they do not release toxic gas into the environment, unlike halogen-containing material.

Halogen-containing material releases toxic gas to the environment which also has carcinogenic effects on humans after exposure to such gas.

Halogen-free materials have a higher flame retardancy than halogen-containing materials.

This makes halogen-free material suitable during the fabrication of printed circuit boards as there is a reduced chance of fire injury and accidents.

Halogen-free materials have low moisture absorption, unlike halogen-containing materials.

This is because there is a reduction in the chances of hydrogen atoms from bonding with hydrogen bonds.

What Elements Are Contained In Halogen Free Material?

The main elements replacing the halogen elements include;

  • Phosphorous: after the decomposition of phosphorous it forms a carbonized fil after dehydration on the surface of the polymer.

This coat acts as an insulator to the insulating resin distinguishing fire when the insulator comes into contact with air.

  • Phosphorous-nitrogen: its assists in generating a non-combustible gas which helps in flame retardancy.

How Does The Cost Of Halogen Free Material Compare To That Of Halogen Containing Material?

Halogen-free material differs greatly from halogen-containing material in terms of cost.

The cost of halogen-free material is relatively high than that of halogen-containing material.

This cost difference reflects from the economic point of view.

For instance, in most cases, halogen-free materials used in fabricating printed circuit boards are very hard making it hard to drill through the printed circuit board.

The physical properties of the halogen-free material reflect the lifespan of the printed circuit board.

In most cases, you will find that this period reduces by 25% due to the hardness.

Therefore, while selling the halogen-free printed circuit board the cost will be relatively high.

Additionally, halogen-free printed circuit boards are very expensive due to the cost of prices and also the processes involved during fabrication.

What Levels Of Halogen Free Are Recommendable For Halogen Free Material In Printed Circuit Board Fabrication?

The levels of halogen may vary depending on the independent entities since the restriction is not set as a rule per say.

However, according to the International Electrochemical Commission, the levels of halogen elements should be 900 parts per million.

The Research of hazardous substances has similar level restrictions as the International Electromechanical Commission.

Among these, there are other halogen standards in the market with different levels of halogen content.

What Distinguishing Features Does Halogen Free Material Have?

Halogen free PCB material

Halogen free PCB material

Halogen-free materials not only are environmentally friendly but rather contain features that make them stand out and recommendable.

These features include;

Co-efficiency Of Thermal Expansion

The co-efficiency of thermal expansion of halogen-free material is normally 10% lower than that halogen-containing material.

This is a result of low molecular mobility in halogen-free printed circuit boards unlike in halogen-containing material when heated up.

Longer Throughput Hole

This is normally a result of lower co-efficiency of thermal expansion hence increasing reliability of the halogen-free printed circuit board.

Moisture Absorption

Halogen-free materials have relatively low moisture absorption, unlike halogen-containing materials.

The tendency of hydrogen atoms bonding with hydrogen is minimal in hydrogen-free material compared to hydrogen-containing materials.

Better Insulation

Halogen-free material provides an insulating substrate on the insulating resin in the air which distinguishes the fire.

Good insulation also reduces the breakdown voltage in the halogen-free printed circuit board.

Halogen-free Materials Have High-frequency Performance

Halogen-free material turns to be the best choice at relatively low cost but works best in high-frequency applications.

Halogen-free Materials Have Better Thermal Stability

When it comes to stability, physical appearance, and appearance, halogen-free materials are more stable.

The monomer molecular Tg and weight increase since the content of phosphorous and nitrogen are high in halogen-free material.

Dissipation Factor

Halogen-free material used in printed circuit board fabrication has a low dissipating factor which in turn minimizes heat loss.

Does Halogen Free Material Have A Negative Effect On The Environment?

Absolutely no, halogen-free materials do not have any negative effect on the environment, unlike halogen-containing materials.

Halogen-free material contains elements such as phosphorous and phosphorous-nitrogen which replaces chlorine and bromine elements in halogen.

Halogen-free material produces an insulating surface on the insulating resin in the air which distinguishes fire.

More so there is the production of non-combustible gas which increases flame retardancy.

Therefore, there is no emission of any toxic gases which means no hazards to the environment.

This makes halogen-free material the best option during the fabrication of printed circuit boards.

Is Halogen Free Material Ecofriendly?

Yes, halogen-free materials are very eco-friendly. This implies that they do not pose any hazard to the surrounding environment.

over the years there has been an increase in demand for environmentally friendly electronics.

This is one of the reasons why their adoption of halogen-free material during fabrication of the printed circuit boards used in electronic products.

Halogen-free materials have distinguishing features such as dielectric constant, dissipation factor, and moisture diffusivity which distinguishes them from halogen-containing materials.

What Are The Applications Of Halogen Free Printed Circuit Board Material?

 Halogen free PCB

Over time there is a constant increase in demand for halogen-free material used in the fabrication of printed circuit boards.

Halogen-free materials are environmentally friendly hence the increase in demand for the halogen-free printed circuit board.

When it comes to moisture diffusivity, the dielectric constant, dissipation factor of the halogen-free material is different from that of conventional PCB.

Ideally, halogen-free printed circuit board materials can be used in all applications and industries with the usage of electronic printed circuit boards.

This application ranges from consumer electronics to large usage such as industrial automation.

There is a great variance of the halogen-free printed circuit board to that of the normal printed circuit board.

This variance Is basically in the percentage of chlorine and bromine making halogen-free printed circuit board more suitable.

The most typical applications of halogen-free printed circuit boards include;

  • Mobile and wireless devices
  • High-end computing
  • Signal integrity
  • Servers
  • transportation

Why Is Halogen Banned In Printed Circuit Board Materials?

Halogen contains elements that are high flame retardance.

These elements include bromine, chlorine, iodine, fluorine, and atastatium.

Because the flame retardance, most of these elements will be used in the fabrication of printed circuit boards.

You will commonly find most printed circuit boards such as FR4 printed circuit boards and CEM3 printed circuit boards are made of halogen materials.

In this case, such printed circuit boards containing halogen flame retardant materials harm the environment.

When these printed circuit boards heat up, they emit large volumes of toxic gas which has an unpleasant smell while burning.

The emitted gas poses a great threat to the environment and also results in carcinogenic effects on humans.

For instance, the use of polybrominated biphenyls is no longer in use due to the above-stated effects. Laws have been enacted to prohibit the use of halogen on any printed circuit board electronics to ensure sustainable development.

Which Elements Have Replaced Halogen In Printed Circuit Board Materials?

Ideally, the main components of halogen include chlorine, bromine, fluorine, and iodine.

These elements have a negative effect on the environment due to the release of toxic gas while burning. To curb this problem there has been a replacement of halogen-containing printed circuit board materials with halogen-free materials.

Halogen-free material comprises phosphorous and phosphorous nitrogen elements.

When you heat phosphorous it decomposes through thermal decomposition to form phosphoric acid. This acid loses water so fast to forms a carbonized film polymer resin surface.

Ideally, the insulating resin contains an insulating surface that is in contact with air to distinguish the fire.

This makes it possible to achieve the flame retardant effect.

Phosphorus nitrogen on the other hand generates a non-combustible gas during the combustion of the polymer resin.

This gas assists in flame retardancy.

In this case, halogen-free materials are preferable during the fabrication of printed circuit boards.

How Can You Gauge Performance Of Halogen Free Materials For Printed Circuit Board Fabrication?

Restriction on the use of flame retardant materials on printed circuit boards has led to a reduction in the emission of toxic gas which has a negative effect on the environment.

In addition to this, there is a high improvement in terms of performance of the printed circuit board since the adoption of halogen-free materials for the printed circuit board.

Some of the major improvements include;

Water Absorption

Nitrogen-phosphorus oxygen resin has relatively low electrons of both phosphorous and nitrogen.

This means the chances of hydrogen atoms bonding with hydrogen in water is very minimal as to that of halogen.

Therefore, the water absorption rate of halogen-free printed circuit board material is low than that of halogen-containing PCB.

High water absorption rates affect the reliability of the printed circuit board.

Insulation

With the substitution of halogen elements with phosphorous and nitrogen, there will be a reduction in the polarity of the molecular bond.

This polarity reduction results in a voltage breakdown and also an improvement in insulation resistance.

Thermal Stability

Halogen-free materials result in increased performance of the printed circuit board.

The content of phosphorous and nitrogen replacing the halogen elements in printed circuit board is high.

This increment is high on halogen-free printed circuit boards than on conventional printed circuit boards.

Normally, during heating, the molecular mobility of the halogen-free printed circuit board reduces than that of a conventional board.

This results in relatively low co-efficiency of thermal expansion in halogen-free printed circuit boards.
