I'm looking at stencil printers, particularly those that can produce good repeatable prints on finepitch boards with minimal setup and training. I would love to find a printer that does auto x-y-theta alignment (would like a system that aligns sten

Steve, I'd stop worrying about the in-line feature of the printer, I've never really seen an in-line system that wasn't capable of batch operation and there will be very little, if any, cost saving associated with going batch load only. An in-line m

Hi Gary, With plastic BGAs it is more difficult to remove the trapped moisture because of ground planes in the substrate. If your parts have been sitting around for a long time they may be soaked with moisture and in some cases the 48 hours bake cy

Are you trying to tie someone to an agreed wastage level or are you being tied? What machines are you talking about? What components are you talking about? The only acceptable wastage level is zero: but you can't get to zero until you've had some was

There are a few variables that you have to consider : 1. Hours available on Wave Machine ( are other products going thru the same wave) 2. What beat rate are the boards being supplied from previous station?i.e. do you envisage the waveto be a bottl

There are no requirements acceptance criteria for baking of board assemblies. What are your customer requirements? The common reasons people choose to bake PCB are to prevent: * Delamination of multilayer boards * Measles, particularly on double si

Here is what you need to do if you can, Since you want to shporten the bake time you need to increase temp. weigh a board prior to your current bake process (you need very hi resolution scale for this) weigh the same board after current process a

| Scott - Good to see things are going well for you. With regard to your comments, Quad has introduced a complete line of Semi-conductor/APT machines (Q Series) that support both SMT and Semi-conductor applications. The machines were introduced in
