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

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.

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

I do not know if you want selective wave soldering or selective point soldering? If you have good budget say, less than US$200k Vitronics is best for wave selective soldering. However, if you have low budget say less than US$100K I suggest ACE or K
