I looked at a number of small bench-top batch ovens and saw two things. First, they got VERY expensive when you got above the very smallest units. Mine will fit an 8 x 12" board. I still have to do one that size and see how uniform the temperature

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

Hi Felix, First thing to verify is that your supplier is actually suppling you with the correct material. China is known for not keeping with the requested materials and will substitute if not controlled. I would recomend ITEQ, TUC or Nan ya for of

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

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

I have been using an Advantek machine for years. It is a manual load and really works good. Rarely do we have problems. When we do its because we got parts from an egineer that dumped a tube of parts out on their desk to get one part and then put the

I would probably try to get my boss to spring for a digital anemometer (air velocity meter) and figure out what my velocity needed to be to get the specified airflow. Then just check it daily before production starts and when it starts to slow down,

FYI, Here are the steps in which we take to get approval. The stencil gerber layer needs final approval through our Engineering dept. What they do is send in a gerber layer from the stencil house and lays it over the current solder paste layer and ve
