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

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

Steve, Currently we are using selective pallets and the best piece of advice is to find a supplier that will be able to handle the requirements of the selective wave process, for example proximity of chips to PIH devices, and pallet thickness etc. We
