Since you are restricting the outward flow of injected material to basically mimic the package dimensions that would force you to design some sort of coffer dam beneath the part to contain the injected material. One alternative to your quest could b

Hello Again John, Are you injecting a like material currently? How are you doing this with your current process? Is this material being used specifically because the customer identified it as such? If this is not a current process for you, how do

| To aid in heat dissipation of our PCB, we would like to try having copper fill areas on the board that are hot air levelled and not covered with solder resist. Then, when the board is reflowed, solder paste would be applied and then solder. Has any

Iman On your situation: As an earlier poster stated, your options are limited to opening you stencil aperture to compensate for the paste lost to the via. On your designer's belief that "it helps in heat dissipation": Could be true, but: * Hole wil

Robert McKeown Company makes thermally conduct Al tape. KIC did a study on which method (Kapton Tape, Aluminum Tape, Hi-Temp Solder) is the most repeatable. The study can be found in their website: http://www.kicthermal.com Al Tape placed 2nd, and

I'm looking for information on a company called AI Technologies. They make conductive adhesives and thermal management materials for attaching dice and heatsinks. Any feedback from users would be appreciated. Thanks, Chrys

KIC Thermal Profiling did a DOE [Nepcon West 1999] [you probably can find it posted on their site] on thermocouple attach. Comparing the reliability and repeatability of thermocouple attachment methods: * High temperature solder was found to be the

| Can anyone steer me towards a supplier of heatsinks suitable for use on a PQFP 160. Before you shoot me down in flames, I know that I am not going to get much heat away from the die because of the plastic but the application is such that the board

| We have a need to bond Flatpack and Quadpack components to the circuit board. The adhesive should be quick curing, repairable and have a low modulus. It does not have to be thermally conductive (but it would be a plus). The components are current
