"What do I Really Need" is a subjective question.It all depends on who you ask. I have been in small mom and pop shops that were running BGA's and they were doing some scary stuff.(I wont go into details) In order to put a correct process together y

Profiler is a MUST, along with at least one board you can scrap. Permanently attach TC's and use it to monitor your oven. You really shouldn't use it more than 5 or 6 times before getting a new one but if you can't understand your reading might be of

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

We had a customer that had 5 BGA's top and 2 bottom and several other assemblies that had 4-7 total BGA's that required WS. Our average build quantity was 2200 boards a month. We used high end Maytag dishwashers and a little Amterge(SP?) Took them t

The tubes don't fit the feeders? I have a Contact Systems vibratory feeder base on my CSM84. It comes with 8 lanes of SOIC only. Well, I use a wider variety of the small chips, from SSOP to wide SO's. The feeder base has some threaded holes in th

Hello. We have currently a big problem with our Reflow owens getting very dirty very fast. It's like a thick layer of "dust" on all parts in the preheat and the beginning of the cooling zoon. We dont have that all the time and it's seems to be from b

Thanks for your replys but I can't figure out why this problem is so much bigger in one owen when we run nearly the same mix in both our lines and we use in 99% of the production only the same 2 different pastes, lead and leadfree. The pastes we use

Lead Free is probably worse as it contains something like 25% more flux by volume than Leaded. But is unusual as No Clean organics usually volatise off and rosins are non volatile so should not accumulate readily unless mixing with other gases in the
