All y'all, We use two methods to secure/stake jumper wires to boards: 1 Jumper wires that "magically" bond themselves when heated with a "U" shaped tip on a soldering iron. 2 Loctite 382 Tak Pak We use Tak Pak "99&44/100ths" more often than the "magi

Masdi, Try board shunts. They are hi-temp rubber strips with grooves cut. They can be popped on and off with ease and are much faster than taping and considerably cheaper. They also work great for masking goldfingers prior to wave soldering. Contac

200 boards/Hr and oven will reflow ~180 boards/Hr but the P&P machine will only place 700-950 CPH when setup is taken into account. Minimum pitch is normally .020" and we place an Avg. of 491 TSSOPs and 217 BGAs a month. We don't even bother with 04

Dear Maurice, Alcohol is a very "vertically oriented" cleaner. It cleans only a selected few types of solder paste. There are also numerous reports of fires and explosions associated with alcohol stencil cleaners. Plus, alcohol stencil cleaners us

| Does anybody know if a contraption exists that will minimize a PCB's tendency to become slightly bent after reflow? We have a new product that we're planning to assemble in a couple of months. The board is 9.7" by 13.4" and it is imperitive that

| Y'all: IPC set-up a site addressing the environmental issues of the printed circuit fabrication industry. Some of it is interesting and applicable to the assembly business as well, even though not aimed directly at assemblers. IPC has recently t
