3 different A12 tools and the same error could be a problem with the tool holder or a parameter. I suppose the locking tabs in the holder could be worn or bent and you could try removing one of the pins from the tool and setting it in a different loc

Can you describe the failure mode of the soldering defect, i.e., is it failing to meet the height requirement for a castellated termination due to not wetting of the component terminations, or not wetting the pads sufficiently, or....? We install a

I would recommend quik-tool. Jim Bernhard essentally the inventor of Grid lok left when they went to DEK. Started quik-tool, we use grid-lok in our printers, quik-tool in our Panasonic P&P instead of support pins. Like quik-tool alot more. JBernhard@

Avillaro, I don't have hands on experience with Vapor Phase equipment, but my guess is that it will work better for thick boards like yours. Trying another chemistry is a logical move. May be it is worth trying the fixture for connector flatness as n

As long as pressure is set properly (may require re-adjustment when adding / removing modules) then have not seen / heard of issues with damage to bottom side components. This assuming that rubber tips are in place and in good shape. I have a custome

A solution that could placed on any machine is a first check that places a component in a fixed location and then the 2 pin component is read with a meter like a HP component measuring system. Similar for transistors and FETS. IC's are probably not s

Hi everyone I have problems welding QFN components in a 10-zone reflux oven, we cannot make a welding fillet that covers the entire QFN pin. Currently we use paste T4 - 63Sn / 37Pb. I enclose the curve of the oven profile. Any help or support on this

We are having issues with solder flooding some through hole pin receptacles which have an organic fiber plug on the soldering end. Anyone else use these types of receptacles and soldering with selective solder. Appears the plugs may be not sealed w

I've done over printing for Pin in Past applications and you'd be surprised how much you can over print and still end up with an acceptable solder joint and no solder balls. As others pointed out, there are a lot of variables involved, so trial and

Are you getting the same solder issues on all of the components on the board? Any consistency in the ones that come up with no-solder? Same pins, same orientation, etc? Could be a solderability issue on the component or pads. I hate random issues
