Which are the Different Flame Retardant Mechanisms used in Isola PCB?

Flame retardants satisfy their role chiefly through either chemical or physical action.

Physical action of Isola PCB flame retardants can be categorized into three modes;

  • Cooling:Additives trigger an endothermic process that cools the substrate down to a temperature lower than that needed to withstand the combustion process.
  • Protective layer formation: A gaseous or solid protective layer shields the combustible layer from the gaseous stage.

The oxygen needed for the process of combustion is excluded and transfer of heat is hindered.

  • Dilution:The system integrates fillers that on decomposition generate inert gases, which dilute the fuel in the gaseous and solid phase.

This ensure that the system does not exceed the minimum ignition level of the gas blend.

Likewise, the chemical action of Isola PCB flame retardants can be categorized into two modes;

  • Solid phase reaction:The flame retardant promotes the formation of a carbon layer on the surface of the polymer.

This can happen through the flame retardant dehydration creating a carbonaceous layer through cross linking.

The resulting carbonaceous layer serves as an insulation film, hindering the material from decomposing further.

  • Gaseous phase reaction:There is interruption of the free radical medium of the process of combustion that occurs in the gas phase.

This in turn stops the exothermic processes, cooling down the system and suppressing the flammable gases supply.

Rogers PCB

Rogers PCB

Which are the Main Types of Flame Retardants used in Isola PCB?

You can choose any of the following:

· Halogenated Flame Retardants

Halogenated flame retardants make part of the largest category of flame retardants utilized in Isola PCB.

Halogens consists of 5 chemically-linked, very reactive non-metallic elements within the periodic table’s group 17.

They include Astatine, Iodine, Bromine, Chlorine and fluorine.

The synthetically formed element 117 is found in group 17 and can as well be categorized as a halogen.

However, Astatine and element 117 cannot be considered for making flame retardants.

This is because Astatine is one of the rarest elements that exists on earth only due to radioactive decomposition of heavier elements.

On the other hand, element 117 is completely artificial having a half-life lower than 1 second.

· Non-halogenated Flame Retardants

Compounds containing phosphorous are the most common in the group of non-halogenated PCB flame retardants.

DOPO is the popularly used phosphorous compound, which is reacted as supplemental flame retardant.

The mechanism of the flame retardant is that thermal decomposition converts the phosphorous compound to phosphoric acid.

Subsequently, the oxygen comprising polymer gets dehydrated by the phosphoric acid and results to charring.

Which are the Micro-sectioningSteps Isola PCB Fabrication?

Also known as cross-sectioning, micro-section is a method applied to conduct a failure mode inspection or to characterize Isola PCB materials.

It is as well important in revealing an interior segment of a PCB.

Being a destructive process, it needs specimen encapsulation to give protection, support and stability.

Isola PCB failures that you can investigate using micro-sectional analysis comprise of:

  • Raw material assessment.
  • thermo-mechanical failures
  • component defects
  • Shorts or opens
  • Voiding
  • processing failures associated with solder reflow

A micro-sectioned Isola PCB may be efficient for observing and examine a number of conditions.

Cross-sectioning is normally employed in failure analysis to evaluate comparisons of PCB materials by variations in structural forms.

These variations can express damage by fatigue, thermal cycling, or embrittlement.

This destructive method of analyzing the quality of PCB works by revealing cross-sectional outlook of a microstructure at a particular plane.

The plane is usually the axis of vias or through holes within accuracy tolerance of +/- 10 percent of thickness of plated material.

Since it is a destructive analysis instead of a real PCB, test samples are always utilized from the same printed circuit board.

The micro-sectioning process starts with preparation of sample.

You identify the section of interest and mark it carefully.

It may be essential to remove components from around the section of interest. You then follow this by the:

  • Mounting;
  • Sawing;
  • Grinding;
  • Polishing, and
  • Staining of the sample

Eventually, you record and analyze the findings depending on the images.

At the end of these steps, the section of interest is prepared ready for SEM analysis or optical microscopy.

Micro-sectioning may be a very instrumental technique for the analysis of Isola PCB.

Thus, the process should be customized for the parts of the printed circuit board.

Which are the Factors that Affect the Permittivity (Dk) and Loss Tangent (Df) of Isola PCB?

The key factors that affect the permittivity and loss tangent of Isola PCB include:

· Resin Content

Resin content percentage differences have substantial impacts on the Df and Dk values.

The percentage of resin content differs depending on glass style, target thickness for a specific glass style, and fabrication tolerance.

Different Isola PCB laminate thicknesses require different glass styles and eventually varying resin content to attain the needed thickness.

· Temperature

The substrate electrical performance will differ with the PCB’s operating temperature.

You should factor in the effects of materials’ increased temperature because of localized heat produced by the parts installed on the PCB.

Using lower Df and lower Dk Isola PCB gives a steady performance through a broader temperature range.

· Differences in Construction

The characteristics of PCB laminate are based on the construction since each is created utilizing different resin content and glass style.

Knowing the differences in Df and Dk values for sole ply and dual ply PCB laminate constructions for similar thickness is essential.

· Resin Systems Differences

Based on resin content, every resin complex will have varying Df and Dk values.

A popular mistake is substituting one resin system with another without completely comprehending the variations in material performance.

This commonly results in Isola PCB that do not work totally.

What is the Relationship between Glass-to-resin Ratios on the Laminate Dielectric Properties of Isola PCB?

Laminates employed in the fabrication of Isola PCB are complex materials constituting of a resin matrix, copper foil, and reinforcement.

It is possible to calculate the dielectric constant of a printed circuit board laminate.

There exist a number of theoretical prototypes that have been advanced to estimate the dielectric attributes of a specific laminate composite.

The primary factor in these prototypes needs comprehension of the dielectric characteristics of the reinforcement and resin.

Generally, the key factor affecting the dielectric features of the consistency of the laminate is the glass-to-resin ratio variation.

The measured dissipation factor and dielectric constant of the complex will change when you vary a number of parameters.

Variation of frequency of performing the measurement or the laminate thickness by removing or adding resin can bring the change.

Thickness variation are typically because of differences in resin weight per laminate’s unit area and the glass fabric dielectric thickness.

The dielectric features of resin have an instrumental purpose in determining the general dielectric characteristics of an Isola PCB laminate.

Laminates manufactured from resin systems having lower Df values compared to glass generally have lower Df measurements with slimmer glass.

However, resin systems having higher Df compared to glass offer lower Df values with thicker glass and lower Df with slimmer glass.

What is Rheology in the Fabrication of Isola PCB?

In the manufacture of printed circuit boards, rheology is the study of materials flow when subjected to pressure and heat.

It enables you to characterize a material’s viscosity as a function of applied shear, heat rise rate and temperature among other factors.

This allows you to obtain data related to press lamination.

The standard model for describing the rheology of a PCB materials entails two parallel plates having material to be designated in the middle.

In the pattern, one plate drifts parallel to the other.

The impedance to movement designates the viscosity of the PCB material in the middle of the plates.

Is DSC Testing important during the Construction of Isola PCB?

Differential Scanning Calorimetry evaluates the heat flow changes in PCB material as it is heated from room temperature to some preset maximum temperature.

Alternatively, DSC is measurement of heat flow changes an Isola PCB material cools from the maximum temperature to a lower temperature (beyond Tg).

It is referred to as “differential” since there is usually an aluminum reference determined at the same period as the sample.

This makes the “difference” between the sample and the reference the real measurement.

Chemical reactions and several physical changes, like melting lead to the release or absorption of thermal energy as they happen.

By assessing the thermal exchanges, the DSC captures a sequence of the physical and chemical state transformations that occur in the sample.

DSC testing of can show a great deal about the Isola PCB resin systems you are utilizing in comparison against those of recognized material.

Moreover, you can determine certain or all of these parameters from the Differential Scanning Calorimetric testing:

  • The melting point of the PCB resin system.
  • Temperature at which cure starts and its duration.
  • Extent of prepreg aging.
  • Distinction in cure between B-stage and C-stage layers within a multilayer PCB.
  • The extent to which the laminate is cured.

DSC testing of Isola PCB can as well provide a measure of the glass transition temperature of the epoxy systems.

This is dependent on establishing energy variations related to a variation in the relation between amorphous and crystalline sections within the polymer.

However, polyimides do not display this transformation as distinctly.

Therefore, the Tg happens across a broader scope than epoxy.

This makes Tg sensing more challenging by DSC in comparison to TMA.
