If you are lucky, you might be able to chip the solder off the fingers with an Exacto knife and then polish it up with a pink eraser. This does work if the solder on the fingers isn't wetted very well. Russ

Does anyone have any experience with underfill of HD connectors? New customer wishes to underfill 6 HD connectors that have been pressed into PCB. Capillary action is causing the conformal coat to wick up into connector. Material is acrylic.

Yes, you need work with supplier to see if can run pin in paste for these connectors, even do some experiments. A step-up stencil would be good for these connectors, also connectors pin size and length match with PCB hole design.

Certainly automatic placement, preferably with vision system assistance will yield a more repeatable process. Process repeatability (paste deposition, connector placement, reflow cycle, etc.) will be your key to success here. Another possibility yo

Hi Dave, ASG in Florida (www.goasg.com) manufactures machines specifically to pick and place pressfit connectors, including vision inspection of the pins. They also manufacture a line of electric servo presses for pressfit connectors. I would be hap

The issue is surface tension around the connector. Your tip needs to have more surface tension than the pins of the connector as it forms a cluster when being soldered. When I used to solder superfine connectors with a metcal iron it had a horses hoa

We are using our selective solder machine to solder a backplane with sixteen (16) 4x48 pin 0.080" connectors. Our first pass yield is about 85% meaning that 85% of the connectors come out with no bridges. Not quite as fine pitch as your connector a

We had a similar issue and it was fixed by trimming the connector so there was barely enough lead protrusion through the board to show a discernible lead. We had to get a special plate and small machine to cut the connectors, but we haven’t had a bri

We're close to receive an assy including one VHDM connector, I'd like to receive any info to be able to place this part properly, and if possible, to know if there is any automatic equipment to place them

Does anyone have information on any automatic machines that place pressfit connectors (manufacturers, cost, websites, etc.)?
