Many times we manually add flux from the top side for good fill.

What is your solder pot temperature? We found that on a 0.093" multilayer board increasing the temp of the lead free solder from 300C to 315C helped with the barrel fill.

You're thinking correctly in trying to improve your process. Can you change to a more active flux? Look at the copper that connects to the center pin. You may need to relay-out the board to add a wagon wheel style thermal relief in that area.

In those cases where we have a 3.2mm thick, 16-layer board with several GND layers, do we still need ground connection to each and every layer (with thermal relief) or, skip part of the ground patterns? Will it help soldeing rising. I can't reach mor

have you considered intrusive reflow? I ran a product similar to what you are describing and the only way we could get sufficient holefill consistently was by this process.... there may be obvious reasons why you cant but worth a shot if you can- it

I am a user of an Ersa Versaflow 3/45. I was wondering if anyone could share some process pointers. I have a 0.125" multilayer PCB that I am having problems consistently achieving 75 percent hole fill on a mini-coax connector. The coax connector ha

Hello, We have recently bought ZipaTec select 250, we are having problems with offsets. Somehow the offset of fluxer, wave and preheat dont match one another or the program we create. The previous owners are of no help. The main question i have

Is there anyone on here that is currently using a RPS Selective Solder Machine? Rhythm SS ?

We have been using SN100C in our RPS Rhythm selective solder machine since we bought it in 2008 with good success. No issues with the solder pot. We are setting the pot temperature to 300C.

Thanks for all the remarks. I am tending toward the move the pot method. I am concerned about parts tilting from square if moved or held at an angle. I won't need to deal with board pallets, board clamp mechanisms, etc. Plus I found the moving board
