I work with lines MX200l and MX 200LP, one of them is with camera analogue the others with digital cameras, the oldest one (analogue camera) is faster than the others, but there is a line that must have a delay in the pick and place, someone knows wh

You can get a better Kapton tape (you must be using the cheap stuff) that leaves no residue. If that fails then you can get edge maskers that slide overtop of the finger and they are reusable. Or you could get a solder pallet made for the assemblies

I would recommend the following chemistries: Zestron Vigon SC200... Good but very $$$$ (703) 589-1198 Vertex (sold by Petrofirm and Alpha Metals)... Won't last as long as Zestron but must less $$$ (904) 261-8286 Kyzen... Also very good (800) 84

So correct me if I'm wrong: you are using a conventional oven (not VP, otherwise you must have mentioned), your big electrolytic caps go through a lead-free profile, which requires 30sec minimum at 230, but your time above 200C on the caps is less th

We're not familiar with Loctite 3606. Adhesive bond strength must be adequate to survive handling forces between the adhesive cure station and the soldering station. At the soldering station, the adhesive will soften during the preheat stage and in

We are required by most of our customers to apply a serial # to the boards that we build. As the PC boards have been getting smaller and open areas on the board are getting scarce we have been forced into using smaller and smaller labels. I am lookin

You can buy an awful lot of stencils for 200K. Unless you are running "special case" products I'm not sure how the cost can be justified. We get our stencils next day with no added charge. The MY600 must use specified paste chemistries that are no

I have about 200 PCB's from which a 20mil pitch QFP must be removed, cleaned and re-used (will place them back in trays for the P&P machine to place the parts on new boards). My intitial concern is: how can we remove the parts in an efficient manner?

I don't think it is a good idea to run your own board in house. The cost will be higher than let the contract out company do it for you. If you are looking for a Smt line.. You must spend atleast $400.000 for an use equipment. Printer= $100.000 Pick

| | Hi All, | | Any one experince BGA-chipset warp about 10-15mil after removing | | from PCB? | | FYI, the rework temperature for preheat was 170C from room | | temperature about 30 seconds, & BGA was removed at temperature | | between 190-200C.
