While I agree that you need to see an MD ASAP, it might help your provider to actually know what you were breathing, and I would worry way less about the materials in the components than I would about the flux from the solder paste. Edited to add, a

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

Sumote, I suggest DESCO ESD safe het gloves, these gloves have a polyester exterior fabric with woven conductive fibers to ensure static protection. Inner lining constructed of material for use in heat assembly processes, can with stand 200�F maximum

Dear Sumote, I would suggest DESCO ESD safe heat gloves, we are using them at our facility, these gloves have a polyester exterior fabric with conductive fibers to ensure static protection. Inner lining constructed of material for use in heat of 200�

I doubt that the interposer is FR4, it's more likely to be BT. Warp during reflow is a function of material a reflow recipe. Your ramp is too fast and is causing the interposer to bend like a potato chip.

I learn from Senju Metal, they have a formula with certain percent of Ag and Cu can elimate the tombstone. The hint is the eutectic only one reflow and the new material have two reflow. Please let me know your result. Rgds. Dason

Any idea where I may purchase Durapol or Durastone material to fabricate a fixture for use in a reflow oven? Is there any other material (non-metal) that can be used for this application? Thanks!

Our plant in Slowakia tries to convince me that it is not possible to reflow FR2 PCB-material. At this moment the PCB's leave the reflow dark coloured and they are schrinked. I'm still waiting for a reflow profile, because I can't believe that it is

Good info, thanks for passing along. The company I work for (equipment supplier) ran some tests with lead free material in air and N2 environements for reflow. In the air reflow environement it was noticed that the material does not spread, much li
