Ceramic BGA components on aramid pcbs | 3 January, 2000

Dear Sirs:

We use BGA ceramic components in our assemblies. We would like to know if there is a technical problem of SMT assembly and reflow of these components on aramid surfaces.

Yours immediate reply would be appreciated.

Hello Yosef, non woven aramid reinforced pcb's are used where is a need for low CFT (coefficient of thermal expansion). Traditionally aramid pcb's were used in military applications in order to reduce the stress/failure rate of solder joints during thermal cycles. You shouldn't have any particular problems during assembly and/or rework of components mentioned in your message as long as you have a good reflow profile. Regards, Rob Thomas
