What Are The Limitations Of Purchasing A Bare Board PCB?

Further machining on your bare board PCB can prove a challenge when the expertise is unavailable. The person you hire to work on these PCBs should have the relevant expertise for quality production.

Some surface finishes result in an uneven surface, and such a surface is hard to work on if you have to work on it.

These boards are hard to repair once they break or damage, and this is mainly an issue given the nature of bare board PCBs.

Breaking or damage means you have to purchase another set of bare board PCBs. This only increases the overall cost of your PCBs.

The etching process has a negative impact to the environment. This is due to the production of harmful waste to the environment.

Is There Difference Between Bare Board PCB And PCBA?

Yes. There is a difference between a bare board PCB and a PCBA.

 bare board PCB

Bare board PCB

A PCBA refers to a board consisting of all the electronic components that complete the functioning of your electronic product. A PCB is a board that is not complete hence cannot function.

 PCBA

PCBA

A bare board OCB lacks most electronic components and is cheaper than a PCBA.

What Are The Main Methods Of Bare Board PCB Testing?

The two main methods of testing your bare board PCB are:

Flying Probe Test

This test relies on robotic arms with poles to test your bare board PCB’s connection.

The arms usually move along all the connections on your board by following instructions from a computer program.

The advantage of this method is it is affordable and flexible compared to pinned fixture tests.

It is an ideal method for smaller quantities of your PCB that require a slow testing speed.

Pinned Fixture Test

Pinned fixture test relies on pogo pins consisting of springs. The pogo pins test the reliability of the board’s connections.

This method is relatively faster since the pogo pins test all the connections at once.

You can use this method to test large bare board PCB without compromising production time.

The only limitation to this method is it is relatively expensive.

What Are The Advantages Of Bare Board PCB Testing?

Bare board testing is advantageous to your fabrication process in different ways. Some of these advantages are:

Saves On The Fabrication Cost

This helps in reducing the overall cost of manufacturing these PCBs.

Streamlining Bare Board PCB Production

Testing your bare board PCB helps in streamlining your production process.

This is by identifying any issues on your PCB early enough and rectifying them before moving to the next step.

Streamlining saves on time, thereby increasing the production of your bare board PCBs.

Which Surface Finish Can You Apply On Your Bare Board PCB?

Depending on your preference, we have different surface finishes to apply on your bare board PCB. These types include:

HASL

HASL surface finish uses a molten alloy of tin and lead. The process involves dipping the PCB in this molted alloy and removing it.

You then remove the excess solder by blowing hot air over the board surface.

The advantage o this surface finish is budget-friendly since it does not involve many processes and materials. It also has an extended shelf life and is readily available.

Its main limitation is that it results in uneven surfaces making t unsuitable for fine pitching.

The method also results in solder bridging, which reduces the effectiveness of your bare board PCB.

Immersion Tin

This process uses a chemical displacement reaction to give a metallic surface finish to your bare board PCB.

Immersion tin protects the copper surface, thereby minimizing oxidation extending its shelf life.

The advantage of this method is it offers a flat surface finish which allows for further workings on the bare board PCB.

However, it is easy to damage the bare board PCB; hence, you need to be careful when using this method.

The method is also not ideal for multiple assembly processes.

Immersion Silver

Immersion silver surface finish involves immersing your copper bare board PCB in a silver ions tank.

This method is an ideal option for bare board PCB with EMI shielding.

You can also use this method for wire bonding and dome contact. It is an ecofriendly method to use compared to HASL and ENIG.

However, it is not as durable as ENIG since it lacks nickel beneath it.

How Different Is Surface Mount Technology Different From A Through Hole Technology In A Bare Board PCB?

The main difference between surface mount technology and through-hole technology is the physical appearance.

Through-hole requires drilling of the PCB through which the insertion of the components takes place.

Surface mount technology is where you place the components on the surface of your PCB, and you then have to solder the components on the board.

SMT allows for the soldering of numerous components, which increases the functionality of your bare board PCB.

SMT allows for various surface finishes compared to through-hole technology.

The soldering process for SMT is usually automated, while that of through-holes is manual.

Using vias in through-hole technology is possible, while that is not possible using SMT.

How Much Does A Bare Board PCB Cost?

The actual pricing of a bare board PCB depends on the following:

Bare Board PCB Manufacturer

You have different manufacturers from whom you can purchase your bare board PCBs.

These manufacturers have different price tags on their PCBs due to the influence of different factors.

Comparing the different prices available and the requirement for your PCBs can help you get the best price.

However, you have to ensure the PCBs you select meet all the quality standards aside from the cost.

Customer Specification On Bare Board PCB Design

Customer specification includes the number of layers for your PCB and the surface finishes you want for your PCB.

You also have to consider the soldering method and the packaging procedure.

The higher the specifications and the more complex your design, the higher your price for these PCBs. However, you can negotiate these specifications with your manufacturer for a better price quotation.

Quantity Of Bare Board PCBs

Most bare board PCB manufacturers tend to work a minimum order quantity.

Having a lower quantity than their MOQ usually attracts high pricing depending on the design.

Checking with your manufacturer before engaging them can help you get the best price for your bare board PCB.

What Are The Components Of A PCBA?

Depending on its function, there are various components that you can find in a particular bare board PCB. Some of these components are:

Resistors

Resistors help regulate the current flow through the components of your bare board PCB.

They are available in different colors to indicate their value.

Battery

The purpose of a battery in a bare board PCB is to provide the necessary voltage for its proper functioning.

LEDs

These lights are available in some bare board PCBs, and they brighten up when current passes through them.

The current flow through an LED is unidirectional.

Inductor

They help store current and prevent any change in its direction flow.

Diode

A diode helps block the change in the direction of the current flow.

Capacitors

They help hold current and release it when there is demand for power within your bare board PCB.

Integrated Circuits

They consist of components and circuits that contain information for the functioning of your bare board PCBs.

Integrated circuits are usually semiconductors and vary depending on the function of your PCB.

Which Solder Masks Can You Use On Bare Board PCB?

The main types of solder masks that you can use for your bare board PCB are:

Top-Bottom Side Solder Mask

The purpose of this solder mask is to identify a green solder mask layer opening. The process invoices adding this mask on a film or epoxy technique.

The component pin is soldered to the board, with the registered openings acting as a guide. The bottom side solder mask is for flip siding your mask.

Epoxy Liquid Solder Mask

This is the cheapest soldering method compared to the others. The process involves silk-screening the epoxy polymer on the PCB.

This method involves using a woven mesh in supporting an ink-blocking pattern. The function of the mess is to allow for ink transfer on the marked areas.

The final step involves using thermal curing to enhance the quality of your solder mask.

Liquid Photo Imageable Solder Mask

This is a mixture of two liquids that you should mix before application on the bare board PCB.

This enhances the lifespan of your solder mask on the bare board PCB.

It is ideal for screen printing, spray, or curtain coating. This mask results in a thin layer sticking on the targeted area of your PCB.

The use of this mask does not necessitate a plating finish.

How Do You Apply Solder Mask On Your Bare Board PCB?

Proper application of a solder mask helps protect the copper traces on your bare board PCB.

You have to consider several aspects when you are applying the solder mask.

The initial step is to clean the board. Cleaning helps remove contaminants from the PCB’s surface, affecting the application process.

The next step is to apply a solder mask in a coat. This involves loading your board onto a vertical coater for the coating process.

The thickness of your coat depends on various factors like the purpose of the board and the required reliability.

Your bare board PCB then goes to through the pre-hardening stage.

The process at this stage aims to achieve relative hardening of your solder mask without affecting the structure of your PCB.

This process also removes unwanted coat layers from PCB, hindering its performance.

The last step is to harden and clean your bare board PCB. This process makes the solder mask solid, thereby offering solid protection to the copper layer.

How Do I Customize My Bare Board PCB?

There are different ways you can customize your bare board PCB. For instance, you can select the number of layers you want for your PCB.

The higher the number of layers, the more complex your bare board PCB functionality.

customized bare PCB

Customized bare board PCB

You can also have different color solder masks for your bare board PCB.

The color helps in identifying if a PCB already has a solder mask or not.

Choosing the size and design of your bare board PCB is another way of customizing your bare board PCB.

Size and design affect the number of components you can install on your bare board PCB.

The number of components on your bare board PCB affects its efficiency and functionality.

What Are The Types Of Bare Board PCBs?

The common types of bare board PCBs available for your selection are:

Single-Sided Bare Board PCB

This bare board PCB consists of one base material covering a thin metal layer. The metal is usually copper due to its high electricity conduction.

A solder mask covers the top part of the copper layer and acts as a protective layer.

Cost-effectiveness and the ease of fabrication and integration of these PCBs make them ideal for basic usage.

However, they are not ideal for complex electronic applications, and this is because it is impossible to include much information on them.

The common application for these PCBs includes relays, electronic toys, and power sensors.

Double-Sided Bare Board PCB

In this type of PCB, both sides of the board have a metal conductive layer, usually copper.

The presence of holes on the board allows for the attachment of metals on either side of the board.

There are two methods of mounting the circuit on this type of board: surface mount and through-hole technology.

The surface mount method involves placing the electrical components on the boar’s surface and soldering them.

Surface mounting is advantageous since it allows you to insert several circuits on either side of your PCB. This increases the areas of application of such aboard.

In through-hole technology, you insert the metal components through the available holes on your PCB. After inserting the metal components, you have to solder them on the other end.

A double-sided bare board PCB has several applications compared to a single-sided bare board PCB. Such applications include mobile phones, amplifiers, power monitoring, and test equipment.

The pricing for these PCBs is relatively higher than that of a single-sided bare board PCB.

Multi-layer Bare Board PCB

A multi-layer bare board PCB consists of more than one metal layer. For instance, you can have two layers, 7 or 8 layers.

The advantage of this type is it increases the functionality of your bare board PCB, especially in increasing the speed of your circuit.

The presence of insulating materials helps in separating the different layers. Mounting components can either be through surface mounting or hole technology.

Rigid Bare Board PCB

This type of bare board PCB involves the use of a rigid substrate. The advantage of this type is its durability since it cannot easily break.

It is also an advantage because it cannot easily break, which gives you value for your money and allows for complex circuit requirements.

Rigid bare board OCB is easy to repair than the other types.

Flexible Bare Board PCB

This type of bare board PCB allows bending and using it in complex applications without damaging its functionality.

What Is The Difference Between Blind And Buried Vias In Bare Board PCB?

The purpose of a blind Vias is to connect the outer part of two or more layers without going through the inner part of the boards.

A buried Vias connects the inner parts of two or more layers without going through the outer part of the boards.
