Let me give you some good advice You take already plenty of risk going lead-free, DO NOT use halogen containing fluxes in a lead-free no-clean process. Halogens left on the board will convert tin, silver and exposed copper into metal salts over tim

We just tested AMTECH's LF4300 with good results. Excellent reflow/profiling capabilities, good processing. And decent cleaning. I say decent cleaning, because we did run into a small issue. While using Qualitek's LF paste, we experienced a lot o

I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

We do not recommend array sizes. PCB houses take a single board and turn it into a step/repeat that is best fit for their process = cheaper boards I suppose. We then approve this array and build programs and tooling to match. On occasion, we recei

I think everyone has experienced this issue at one time or another. We receive or design one-up's, and let the board house recommend panel size. Unless there's a process specific reason for us to define the panelization. We then approve the array

Sounds familiar. We are trying to get credit for a bunch of boards at this time based on the gerber we approved - not an official print by any means. Unfortunately, we are stuck with the paperwork trail and the 38 junk boards that were ruined in ma
