Hi, I am new in this industry and have purchased a beguinner unut, a 3-in-1 solder, desolder, hot air station. Currently I work on cellphone mainboards. At the moment I only replace single large chips on the mainboard. I would like to be able to repl

Hi, I am located in Auburn Mass (USA) right near Worcester. Now I noticed you talked about micro stencil for a populated PCB, would I need one? Or could I use a syringe to lay a tiny dot of paste since im only replacing a chip or 2 (at the moment)? I

Mark, This is a big topic. Where are you located, it would probably be best to hook you up with someone in your area. Anyhow, lead or lead free should be based on whether the circuits are lead or lead free. I would guess that cell phones would all

Good Morning Vijay, It sounds like the PCB is getting too hot at rework. Is there any way to attach a thermocouple to check actual temps? This would give you an idea if it is your process or your PCB. Good Luck Chris
