to my knowledge it will always be manual insertion,, if you mean reflow, not insertion, I always apply solder to one side, reflow, then apply tacky flux pre print to the already soldered pins, print op side, assemble part then send through placement

Thank you Michael, yes we use a Fine Focus X-Ray machine, we also had some dummy connectors to play with, so we profiled the board until we reached a desirable profile. For placement we used a GSM machine, the only issue we ran into there is the par

Hi Russ, Thanks for the reply -- It is not a double sided board so I guess I will be doing pretty much the same process as you described. I was wondering about was the tool you mentioned -- Is this just a fixture you got made locally or some specific

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

I am not sure if I have seen an article comparing solder joint strength Vs pressfit although I am sure this has been researched by literally hundreds of companies before they felt comfortable going to pressfit. I know one of the issues with solder is

We are having a problem with JST connector ICM-MA50H-SS52-1161 LF SN. After reflow oven soldering we have mostly problem with soldering quality for firs or last leg of the connector. (There is no connection- leg just lays-lift on the solder no wicki
