Do the math first. 10,000 boards a month means 440 boards a day (roughly, and not including weekends). Do you plan 2 shifts or only one? If one, you need to produce a board about every minute if you work an 8 hour shift. If all 110 parts are on on

The smt world is new to me and I have a lot of learning to do. I need some recommendations as to best way to ship partially assembled circuits. The board is question is double sided. One side is smt and the other is thru hole. Our plan is to have th

We have had nsome new products come in that require Bottom side wave soldering (SMT). I have SOIC's 1206, 0805 that are Glued then Wave soldered. I have had trouble with bridging and no-clean residue with these pcbs. I have a Econopak 2 SMT two zone

Is this board going across wave? If not, you are pretty safe to lose the glue process. If it does go across wave you can probably lose the solderpaste and replace your solder stencil with a glue stencil, much faster and efficient than dispensing.

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

Anyone doing a print-dispense-place-reflow process? I've never heard of it being done this way before today. Don't know why, actually, as it sounds like a fairly friendly method provided the adhesives used are happy with a standard reflow profile.

Sorry to disappoint, bud. Believe it or not, this guy's for real. It'll be sad when his investors find out that returns on contacting are something akin to pass book accounts. I'd do something like the prank that you imply, but this is a lame topi

Personally I would go for one alloy it just makes it all simple to control. I have only used tin/silver and tin/copper so far with good process results. Reflow is relatively straightforward, I have had more shorts with wave on tin/copper. To date I
