Thanks for the advice. In this scenario we are designing our own product. Currently we are building at a prototype level with no appreciable wait between reflow passes. The part in question is a 64 pin QFP. We use a BTU VIP 98 with edge conveyor.

We are moving into fine pitch components. 64 pin QFPs and the like. We've chosen an ENIG pcb finish to help with flatness of the pads, but the pcb vendor has asked for a thickness specification. Can anyone provide a recommendation? It seems like

FormFlex and the GridLok system will not work on a semi-automatic printer. They were designed for fully automatic machines. The print table is very shallow on the DEK 248, SMTechs and MPM SPM, UP100 and MicroFlex. DEK should have magnetic base suppor

Ersa Versaflow has a nozzle we use for soldering 70 pin connectors, with smt parts 3mm from the leads. As far as soldering through hole (without the tight SMT parts)It's reliable, easy to program and very good quality joints. Your advantages are spee

Hi all, There are no ground layers which makes the non wetting rate a bit confounding. The foam fluxer has not been cleaned in a while though, while there is a strong evidence of fluxing by running blank paper and looking up the top side

Initial points for investigation are: * What temperatures are you measuring on the leads that do not reflow well? [How does this match with the paste supplier's recommendation?] * Does the component take solder after being dunked in the solder pot? *
