In my past we have used grease that we put in the connector before potting. The grease would keep the potting from flowing into the connector.

Let me start off by saying that although we pot a decent variety of products, we have never been asked to do something like this, so this is not based on personal experience. This is just my gut talking here. I suppose you could use some sort of ca

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 are having difficulty with bridging on a 2x50 pin 0.050" fine pitch connector using our selective soldering machine. It usually bridges at the end of the row, but sometimes it bridges all the pins together as it drags across (solid bridging). I

I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.

We just got new boards in that have ENIG pads. In the past we had a problem with too much gold getting into the wave solder pot from large connectors getting tinned at the wave. Do we have to worry about too much gold getting into the pot with this

1800??? That's not a Mictor part number. Huh? What??? Haaaa!!!! You gotta do what???? 1800 ofem??? Haaaa!!!! Sorry. It�s simple. Just ... * Cut all the SMT gull wing leads on both sides of the connector just above the solder. * Put the co

Cristiano, Are your oxidised components now all on boards ? How many and how many terminations ? If you have any that are still to be used, maybe you can get the supplier / customer to replace them, unless of course they are well old. If you have

Wave solder - Initially high cost but after that it is relatively cheap. Selective soldering with a solder pot such as the Air-Vac PCBRM models - Much lower cost than wave but if you get the right nozzles it is a great process. Solder preforms - s

For selective soldering I would first look at the alloys your products require. Do you run tin-lead, lead free or both? If you run (or may run in the future) two alloys, then look for a machine that has quick change solder pots. Secondly, do your bo
