Wow, 15 degrees C is too much. Is this a new problem or new oven? If it's a new problem several things you can check out. Thermocouple placement may have got knocked into the wrong spot, or it could be dirty. I've seen this happen after a PM and

I think we run our Vectra between 9 to 14 PSI. If memory serves me, I dont think you can set it above 14 PSI. We use VOC free no-clean. Your number seems WAY high. Check the nozzle. You also may need a different nozzle size. We always run a good filt

thanks for replies guys. I have a nearly Full RoHS Compliant bom with 1 device non-rohs. It is a soj28 device rated ( as best as I can find out at 225degC) Production are screaming for these boards - I put a thermocouple on the part and it hits 23

"Surface Mount Techniques has approximately 98 percent of the world market share of large Panel Stencil Printers". It sounds a little bit strange to me, especially since I work for one of the companys listed in their advertisement and it is definite

Thanks Mark and Dave. It sounds like our board design and problem areas are similar to yours, Mark. We talked with our customer about the grid pattern but I'm not sure where we are at with that. In reference to the Tg/Td thread, the material is a

Electronics firms doing business in China need to be aware that while China RoHS targets the same substances restricted by the EU RoHS directive, the China policy stipulates that compliance can only be verified by testing done in accredited Chinese l

Hi guys. I'm hoping maybe some of you can help me with some information today. I'm looking to find out "ballpark" how much a decent board washer would set me back. The one I currently have just isn't doing the job the way I want it. It seems to have

Can be done with AquaStorm 200, with some mods. I worked on a project a few years ago for a military company that needed to clean no-clean solderpaste residues from under LCC devices, we're talking like 2mil standoff. We ended up using a Zestron clea

We are going to start doing rework of Lead Free BGA's. Have always used flux for SN/Pb boards/BGA's with good results. Can flux be used fro lead free as well? Boards were originally assembled using lead free paste and components. Hence, the BGA w

Hi Ronald, We have both, 2x calrod on our leaded delta and calrod/convection on our leadfree, both are IR in 3th zone. Indeed, the forced convection is way more efficient, we can run it at 100deg C, where we would need 300deg C for the calrod for t
