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

Will there be any problems with reflow when using CCGAs on nonwoven aramid reinforced pcbs? thanks!

Found the aramid fabric (Kevlar) on the website you suggested. Which thickness Aramid-and-Fiberglass Sheeting should I get, do I need to buy a strip as well to protect up to 600F? I was going to use PTFE-Coated Fiberglass Thread as it is rated up to

I got it from McMaster-Carr. http://www.mcmaster.com/ They have just about everything you could ever want, but I don't know about delivery to the UK. I think it cost about $40, or about 30 Euros, or about 20 British pounds. The dollar really isn'

Does anyone have information regarding: -Moisture level (wt%) that may cause delamination in PCB�s. -Baking time and temperature if using a Vacuum Drying Cabinett and if using an air oven. (What I�m most interested of is Poly-Imid-Aramid.) -Are ther

Daniel: In response to your questions: * Moisture level (wt%) that may cause delamination in PCB�s. - Certainly, it depends, but 100% moisture will not cause delamination of a PCB. [Now, heating that water is another question, isn�t it? ;-)] *

Iman When you talk about your profile, can we assume you're measuring it on the pads of LGA? Profile the solder paste reflow by placing a thermal couple under the component pad, similar to a BGA. On a slight tangent, as with soldering BGA, paste
