The beamworks new software on teh 100 is great but went to outstanding when the 60 watt leser was installed and the performance went up 60% in speed. The new software requires the temp of the solder for melting and the ammount to be despenced and the

No you're not stupid, they will melt if the top of the board gets real hot. I was lucky most likely in that ours were usually off of the board surface. anything that will hold the weight material will work. Now that I think about it my shot bags w

A thorough analysis is in order because laser point-to-point soldering lacks the flexibility of the bottom sided miniwave systems. My experience showed that heating profiles could be grossly affected by color temperature and thermal mass. This can be

The methods Terry mentioned are good, but our operators are too impatient. Here's how they do site prep, after removing the BGA: * Use a soldering iron to melt the solder at the base of the ball. * Flick the ball[s] from the pad[s] with the solderin

Does anyone have any experience in point to point laser soldering and laser light reflecting off of SMT component 'J' leads down on to the laminate. This appears to be a random situation we cannot understand nor control.

I am building a rugged digital video camera product that essentially is just a sandwitch of 3 parts: #1: front piece is machined aluminum with C-mount thread #2: middle piece is 1/16" printed circuit board #3: back piece is machined aluminum The

Hi, I tried to use high temperature solder (540 - 570F)to connect four spacers on the board. The solder mask around the spacers wrinkled a lot.I can even see a few bulbs around it. I use hot plate and solder rings. After hot plate is heated to appr

Three methods, all work, all require generous use of flux. 1.) Use a heated, electrical desoldering tool with flux. Just be sure that you select a forgiving desoldering tip with a rounded tip end to it so that you do not scratch the pad. Advantage:

We have the standard profile as a template made according to the solder paste specs. For some boards we measure the result at 2 points, on the board itself and on top of a sensitive SOT263 module and adjust accordingly. The solder paste is well kept,

GR@ICS: Are you drag soldering or point-to-point soldering? Keep in mind. Drag soldering mimics wave soldering. Molten solder is contacting and dragging across the solder mask. Keep in mind, too, that "semi-matt" or "semi-gloss" will also tend to
