Dave, Thanks for the info! Yes, I have read the IBM document and realized that I was missinformed about the paste volume. I need 5000 to 5600 cubic mils of paste. Running the numbers I get a 32 mil aperture with a 7 mil step (the rest of the board

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

Mike, To answer your question, Yes we have thru-hole parts on the boards that we converted to double-sided reflow, we use pallets to select solder the leads. I suppose Masking would work, but that's using a lot of mask. Can I ask, whats preventing

Pallets will not work in this case because the wonderful designers put 0402's between the legs and all around the legs of the thru-hole connectors. There are 18 thru-hole connectors on this board and 200 - 0402's around them. The 0603's that are al

We have a granite table out on our production floor. We use the table along with metal parallel bars and a height gauge to measure component height. Some of these boards have components on them that may be ESD sensitive. Does anyone have experience w

Over time, you might see problems with delam., blistering and warpage if using FR4 carriers. Depending on volumes, you might consider using durostone or some robust material like that for the production runs. Keep in mind that switching materials w

Dissipative flooring is not really "conductive" so to speak. what it does is (supposedly)dissipate charge as it accumulates on the surface of mat. Does this mat have a ground lug on it? Responses are correct, unless you can get conductivity between

Hi, Do you have any idea if there is some tool to inspecet if we have the right component on the board ? like a smart tweezer. Also I'm looking to find a tool to spice smt reel. I need that because our buyer told us they will only buy cut tape.

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

The 483 is what we use on all boards except on one where the 353 improved wetting on resistor packs. It worked much better since the parts are LF and this is the same flux AIM uses in their LF solder. Yes, it was recommended by AIM when we discussed
