High Temperature Pcb Laminate

During the pcb manufacturing stage peel strength is tested on one ounce thick copper traces under the following three conditions.

High temperature pcb laminate.

Advanced printed circuit board laminate materials. At pcbcart our high temperature pcb products can handle extreme pcb glass transition temperature rates and retain their integrity so you can use these high tg fr 4 boards with confidence. Glass transition temperature tg. The last three materials on the list are generally used in high frequency pcb applications.

Our laminate and prepreg materials are used in a variety of advanced electronics including network and communications equipment and high end consumer electronics as well as advanced automotive aerospace military and medical applications. Glass transition temperature refers to the temperature at which polymers shift thermodynamically from rigid to soft. For pcbs the tg corresponds to the temperature at which fiberglass becomes amorphous during lamination at high temperatures and under pressure of the different material layers. If an application demands pcb with higher tg value you ll need to opt for a medium or high tg pcbs.

High temperature laminates should have the following protective properties. Copper coated laminate fr4 treated by internal layer imaging is the. It is not the pcb maximum operating temperature but rather that which the pcba can endure for a short time before it deteriorates. Medium tg pcbs generally have a maximum temperature of above 150 c while high tg pcbs are rated above 170 c.

List of some common pcb laminates and their typical thermal conductivity values. High temperature pcb laminates can prevent overheating by offering heat protection for the pcb s components. We have a 99 plus customer satisfaction rate and are well known for our reliable fast service as shown by our customer testimonials. After thermal stress at high temperatures and after chemical exposure.

Beyond typical fr4 maximum temperature. General fr4 tg is 130 140 centigrade moderate tg is greater than 150 160 centigrade high tg is greater than 170 degrees. Picking the right high temperature pcb laminate materials can be crucial to your operation. Why picking the right laminate is so important.

Medium high tg pcb. If you are going to use your printed circuit boards in high temperature situations pcb laminates for high temperature are a requirement. There have been circuit applications which were not high frequency but still used one of these laminates because of the improved thermal conductivity.
