Makes us wonder how well the connections on the > component match with the pads on the board. The pads are actually larger than the leads on the part, but I think we may have figured it out. We believe the conveyor vibration is causing it. When we

First thing we did was visit the profile and we have it adjusted as far as we're willing to take it. I'm just going to make a carrier design in cad and have the board house produce some in their thickest substrate to see how it works out. Thanks.

First, companies should nor be venting solder process fumes into the workplace. Second, you should see medical attention, as Alexy suggested. It doesn't matter what caused you to get sick. Get fixed. Third, if your ex-employer is venting soldering

In a past life we had "board catchers" who stood at the end of our two lines and caught the boards. They were also in charge of transporting the boards to wash and loading/unloading the wash as well. I was never a fan of this approach, bu

We just use a ramp to a cart and the line operator loads them into trays as they come out. There are buffer conveyors or magazine loaders you could use. Or do a little industrial automation with a plc and proximity sensors; combine a ramp and a belt

If the board is just not reaching the temps you need, you could place them in an oven to "preheat" them. When I was building a rather thick board with a copper core I had to do this. Since we were only doing small runs it was feasible, I don't know y

Thank you Clare. After doing some more research, I found they are known in the industry as "Carriers". I did look into that durostone material. They prices are beyond reasonable. My trek now is seeking a material to make planks out of to lay the b

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
