I am looking for the same. IPC 610D does mention about the solder fill based on the class (A,B,C). But, there is no exhaustive study that I have come across. Please let me know if you find any. KT

We use a chunkee trimmer in prep. Cut bend and form all thru hole parts before first assembly.

Can TH component be placed on solder side of Single Side PCB?

Sure. Section 7.4 covers unsupported holes, and defines the usual standards. Clinching, fillet on the plated side, lead protrusion, etc. Cheers, ..rob

I have found that if you keep lead protrusion below the PCB at less than or equal to 0.030", you will not get icicling or "paste pukes"...

Trouble selective soldering fine pitch connectors

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
