Hi Russ, Thanks for the input. We already check our subcontractor mounting of the connector on the board and it seems that the problem is related to some batch of connectors from their vendor. Anyway, i believe that your suggestions on the agreement

Mixing No-clean and water soluble processes

We use the OM-5100 and wash it with relatively good results. Just dont let it sit longer than a few days before wash. We've used Zestron AC200 and A-250 in a batch cleaner set to 140 wash temp for 8-10 min @ the recommended concentrations. We have h

Chris, it was cunning of you to think of this sequencing solution, but speaking from my lofty position of King of the Workaround, I can only suggest this - forget it. Sorry to be blunt about it but you've said that your operators aren't motivated, al

Solder Paste and fine pitch components

Where I worked previously we had some boards with a couple 15 mil pitch parts. The first batch we got all had undersized pads. We had lots of bridging. We had less bridging with bigger pads. The ball size in the paste makes a bigger diffence regar

Hi Daan, What we did in the time was pareto analyses on all board designs to determine the critical areas (mainly design errors) and only inspect those specific problem areas. Every batch had a copy of the PC board with problem areas marked and only

CRITICAL DILEMA! Has anyone run into the problem described below and if so, what was the fix (besides not dealing with this Supplier)? Also, we do not have component manufacturing process experience. We are purchasing a surge resistor that function

We currently run two Quad IVC's (we are very pleased with them) and two Versatronics for simple small volume batch work. We now need an additional machine capable of placing components at least three times as quickly as a IVC. We don't do anything ve

Thanks for all the responses. I do agree with what was said, and can certainly see reasons not to try. I'll write a little more about what we do. We are a defense contractor, and as I mentioned very high mix, low volume. We only have 1 SMT line.

That does sound like a great deal Tsvetan. Can you share any information about who/where exactly you purchased the machines, and which printer/reflow you have? I do have friends and colleagues in China that could ease the process if anything is comin
