Does the change from supplier to supplier as a result of: * Board definition? * Differences in processing at fabs? 3 Specification Fir Tree General Technical Specification 3a Design/Layout: * IPC-2221 * IPC-2222 3b PCB Fab: * IPC-6011 * IPC-6012 * I

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

Drill a hole through the board (or the BGA) and set a thermocouple into the center of the device (in the X Y and Z dimensions) and run your profiler through the oven until you get the temp you need in the center of the BGA. Attach a second thermocoup

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre

You will need to develop your reflow profile which includes drilling a hole through the fab and into the ball for accurate temp measure. During profile/process development you will probably want 3D x-ray (consider contracting that out). Once in prod

I just discovered my reflow oven exhaust had no suction and I'm fixing it now. What I want to know is what happened to my process. FYI. The exhaust from my other oven was getting kicked back into the faulty oven because of this loss of suction. The

Thanks Real Chunks and Davef...Yours input is valuable to me. My inputs towards your question asked below: Questions are: * Why did you tell us the following? "This BGA is installed with heatsink (with hook at both side of the heat sink) manually b

We have had VERY GOOD free tech support from Mydata. However, we bought a refurbished TP9 directly from them. I believe if you by a used MyData machine from someone else there is a fee to register your company and the machine in their system before

Thanks for the link Samir. Although this thread does have some good info in it I don't think it is hitting the exact point I am trying to resolve. This seems to talk to a one profile fits all for running lead and lead free paste. I want to know about
