Hi, I have a QUAD 4C mk2. I taught pickups and places from HHT. If I test them individually (RUN STEP PICK/PLACE etc...) before building the sequence, everything runs ok. After the sequence was built, everything goes wrong. Every PICK or PLACE ends i

My own preference in this arena is towards the forced air convection style preheat, the key being the forced air. Radiant preheat is too slow for some, and IR preheat can have other issues that convection (or radiant) will not. Zephyrtronics has bee

The entire oven is clean there are no blockages and the heater plates are brand new. I have worked with Vitronics technical support and gone through this thing with a fine tooth comb. I have even gone as far as to compare the exhaust and intake cap c

I can't answer your specific question on the floor, but I have some suggestions. The equipment manufacturer should be able to provide the floor loading requirements. A structural engineer should be able to translate that into specs for hte constructi

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not

I have a 208 pin QFP that due to manufacture obsolescence I have to get them form the broker market. I've had several issues with the parts including; bent leads, leads that don't take solder very well, co-planarity problems, and DOA fallout after a

If there is only a single lead free BGA on the BOM, I would suggest a "hybrid" profile. Use regular solderpaste (SN63/pb37) and peak your temperature at around 225C. Allow a bit longer TAL to let the two solders co-mingle at the BGA joints. You are

Yes, car rims (and brass tubas)! You finally helped me get to the bottom of this expensive issue. We fired the culprit. It's the same guy that was using the ultrasonic stencil washer to clean car parts on night shift. It might be snake oil, I don
