High Temperature Pcb Laminate

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.

High temperature pcb laminate.

Beyond typical fr4 maximum temperature. We have a 99 plus customer satisfaction rate and are well known for our reliable fast service as shown by our customer testimonials. Advanced printed circuit board laminate materials. High temperature pcb laminates can prevent overheating by offering heat protection for the pcb s components.

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. Glass transition temperature tg. General fr4 tg is 130 140 centigrade moderate tg is greater than 150 160 centigrade high tg is greater than 170 degrees. If an application demands pcb with higher tg value you ll need to opt for a medium or high tg pcbs.

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. Ordinary pcb materials at high temperatures not only will be softened deformation melting and other phenomena but also the mechanical and electrical properties decline sharply. Picking the right high temperature pcb laminate materials can be crucial to your operation. Medium high tg pcb.

List of some common pcb laminates and their typical thermal conductivity values. Why picking the right laminate is so important. 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.

During the pcb manufacturing stage peel strength is tested on one ounce thick copper traces under the following three conditions. After thermal stress at high temperatures and after chemical exposure. There have been circuit applications which were not high frequency but still used one of these laminates because of the improved thermal conductivity. The bonding ability between dielectric and copper layers in a printed circuit board is known as peel strength.

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. It is not the pcb maximum operating temperature but rather that which the pcba can endure for a short time before it deteriorates. Glass transition temperature refers to the temperature at which polymers shift thermodynamically from rigid to soft.
