Hi SWAG, Hi CL, I've seen the BGA Kapton things, I believe we'll go in that direction as well. I agree with you too CL. Depending on the product, I either have issues or no issues. That's why I was posting here, just to see if it was me (as I a

Sounds like your PCBs are now white tin. Change this to another roHS compliant finish and see if prob goes away. You must get control of the materials that you are being asked to build. Your Customer needs your advice on surface finishes, they sho

Stephen- I'm curious about your statement regarding someone mistakenly thinking it would be a good idea to get more done in China. I fail to see the mistake in such an approach. Consider if DEK or MPM felt that way a few years ago. They would both

Hi Dexter, Your problem may not be with the feeder itself but with the quality of the tape you are receiving. OX3 Corporation performs a peel test on every single line item that is processed through its facility. You may want to check with your cu

we do a similar thing but make the template from paper, we just print out an image from the gerbers (to size) showing both sides in different colours, we set this down on the table (had to work out first where the correct position was) then we place

Check for coplaner leads if this just exists at reflow process, i.e. look at part before oven, turn on 3D at placement machine. If you see after wave solder, the wave could cause coplanarity issues on top as well if you are going slow enough to refl

Hi, Could it be shocks in transit? This is only happening on 1 product, so might point to chassis and packing design. Does anyone know of any shock indicators that we could put inside the chassis to see if the faults are caused by this? I have seen

Hi Peter, Out of the 1.5 billion components we shipped last year, we had 3 components back for solderability issues. All 3 had been taken out of their vacuum packaging and left to oxidize for a number of weeks. We don't see it as an issue, but we

The low cost option would be to buy an old Electrovert with a spray fluxer & fill with SN100C. Saves cost of conversion, and you can pick up old, decent machines very cheap. Talk to whoever sells SN100C where you are in the world and go see some cus

It sounds like it's just failing the laser align step. Try changing the align type for the part to "2" and see if it places it. If it's failing the laser align and you have valid part dimensions I can't help much but you might consider opening up th
