High Temperature Pcb Laminate

If you are going to use your printed circuit boards in high temperature situations pcb laminates for high temperature are a requirement.

High temperature pcb laminate. Why picking the right laminate is so important. Glass transition temperature refers to the temperature at which polymers shift thermodynamically from rigid to soft. If an application demands pcb with higher tg value you ll need to opt for a medium or high tg pcbs. General fr4 tg is 130 140 centigrade moderate tg is greater than 150 160 centigrade high tg is greater than 170 degrees.

Glass transition temperature tg. We work with top pcb laminate providers to bring you a wide range of material options such as enhanced epoxy laminates ultra low moisture materials high frequency ceramic filled laminates ul 94v 0 rated rohs compliant and more. During the pcb manufacturing stage peel strength is tested on one ounce thick copper traces under the following three conditions. Advanced printed circuit board laminate materials.

Medium high tg pcb. It is not the pcb maximum operating temperature but rather that which the pcba can endure for a short time before it deteriorates. 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. 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.

We have a 99 plus customer satisfaction rate and are well known for our reliable fast service as shown by our customer testimonials. The last three materials on the list are generally used in high frequency pcb applications. High temperature pcb laminates can prevent overheating by offering heat protection for the pcb s components. 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.

The bonding ability between dielectric and copper layers in a printed circuit board is known as peel strength. There have been circuit applications which were not high frequency but still used one of these laminates because of the improved thermal conductivity. Medium tg pcbs generally have a maximum temperature of above 150 c while high tg pcbs are rated above 170 c. High temperature laminates should have the following protective properties.

Picking the right high temperature pcb laminate materials can be crucial to your operation. Beyond typical fr4 maximum temperature. Copper coated laminate fr4 treated by internal layer imaging is the.
