The recommended feeder for 0402s and especially 0201s is the green feeder with a 3.7mm spec. We use greens for 0402/0201, white for 0603, yellow for 0805s, and reds for tantalums. They work well, but sometimes you seem to get difficult tape. I hav

We use the Juki electric feeders, I have not seen the mechanical ones. The reel holder is the only problem we have had with these feeders(cheaply built). That said our operators are trained to change a feeder in less than one minute, (originally it w

The ENIG process will yield between 3-7 micro inches (110 - 275 microns) of gold over the nickel barrier. This thickness range is pretty much the limit as this is a self limiting displacement reaction process. Once all surface nickel ions are repl

Hey John: Chrys wrote a good description on calculating flux density a while back. Here is our version of her procedure: 4.3 Determine the amount of flux on the board. 4.3.1 Get a piece of corrugated cardboard and a weighing scale accurate to 0.01

basically the rule of thumb for the 8mm feeder is that you only want one component exposed in the pocket at a time. If you see more than one component exposed you need to go down in size. The reason for this is that if there is another component expo

Downhole solder suggestions, in order of preference are: * Kester Sn96.3Ag3.7. Most vendors do not stock straight tin-silver alloys, whose wallet is that fat? * SAC305 can usually be used in place of one of the copper-free tin-silver alloys in downho
