Printed Circuit Board Material Selection

Material selection for the construction of a printed circuit board is a critical step towards the final product.

Product Application Recommendations

Application recommendations for selection of a specific type of material is based upon consideration of the following:

• Material Suitability
• Best in Class Performance
• Cost / Performance Ratio

Key Questions:

• Will the (PCB / PWB) printed circuit board successfully survive the reflow process?
• Will the (PCB / PWB) be fit for use and have maximum reliability in use after the reflow process?

Specific Material Selection Suitability

The application suitability of a specific type of material is based on consideration of the following parameters:

• Tg - Glass transition temperature
• Td - Decomposition temperature
• Z axis expansion
• PWB Processability
• I.S/T/ performance
• T260 and T288 performance
• Solder float survivability
• Thermal cycling performance
