Hi Dave, The short answer is "not any significant amount" of moisture is removed during reflow. The temperature excursion is much too short. If you look at the physics of moisture diffusion inside a package you will see that only the surface moist

| Hi , | I have not been able to find any good description on how to perform double sided reflow on PCBs.The best would of course be to avoid reflowing the bottom side again but in real life this is not possible. | So when double sided reflow sol

Dear Vicki, If you decide to use high temp paste, I suggest that you verify the rating of the components, especially for moisture-sensitive devices which are normally qualified at peak reflow temperatures of 220-235C. The specified floor life will

Mike: I�d hate to see you making design decisions, based solely on the discussion here, but that this would be an impetus to consult IPC-D-279, "Design Guidelines ... " and take a course on designing reliable boards. Werner Engelmaier (Engelmaier

I'm looking for a double-sided adhesive solution: 1. Strong or permanent adhesion on one side, temporary adhesion on the other side. 2. Can withstand high temperature (lead-free oven reflow) I'm trying to temporarily stick material on a panel using

How high are we talking? 1000 Celsius? KIC Thermal Profiling double sided aluminum profiling tape. I have used at an extreme application of 240 to 300 degrees celsius for 18 minutes. With up to 30 passes with no visible degree of deterioration.

Hi, We have encountered one serious problem that heavy packages falling down during second side reflow, especially for PLCC 84. I believe it caused by temperature profile setting. Any good suggestion would be highly appreciated! Stoney Tsai

There is double sided adhesive that able to withstand high temperature during reflow. `keep the adhesive minimum and appropriate location for securing the FPC on pallet during entire SMT process and easier for release of FPC after reflow process. Tak
