| Is there any way to implement SMT at home? | I want to assemble a prototype board of mine. | How can I hand-solder a 208-pin 0.5 mm lead | pitch PQFP -- lead-by-lead (the usual way), | or side-by-side (partial heating method)? | Alas, no SMD rework

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

Doug, Depending on the machines in question, the release characteristics change. Most of the mechanically driven machines simply stop the vacuum by lowering the nozzle and release the stored vaccum at impact when the nozzle starts to compact back int

Hi Nightbull, I'm with Dave. Don't see the need. Good stencil, good operator, reasonable machine with at least manual vision alignment, good set up, solder paste that satisfies you and the customer, regular maintenance, and how can you go wrong? As

Hi Jon, I recently had the opportunity to look over a used IIIc converted to a IVc. The documentation, software and spare parts supplied with the machine seem more than adequate, however, upon spending several hours cleaning, oiling, familiarizing,

Hello!!! Just to say, I've never even heard about placing parts on double-sided tape for inspection... We always build one board placing parts on paste/glue and inspect it befor reflow. With suppliers specs of 6hours at least, I don't see any prob

cvrgrrrl Your first thermal cycle with imm silver should be the easiest to solder. That you see copper indicates you did no soldering, got no wetting, produced no intermetallics, etc. Tell us again which components did not solder? Wuzzis "plug" t
