Alternate Solders/methods of flex attachment to pcb's

Electronics Forum | Tue Mar 21 19:34:32 EST 2006 | Tom Smykowski

Omar: I dealt with this so called "hot bar" process also, and you're right; it's neither reliable nor repeatable. The goal was to attach a flex LCD display to another flex circuit. The flex LCD was constructed of resin and conductive silver particl

Typical SMT Machine changeover times?

Since you are a HM/LV facility take a look at the feeder design. I noticed that the MyData feeders (that I have seen) peel back a lot of pockets before the pick, so when you change part numbers on the feeder there is a larger waste of components. O

We are also a high mix/low volume OEM and are running Samsung CP45's with quick change carts on both sides of the machine. We currently average 12 minutes of internal changeover time per run with an average of 17 changeovers/day for 2 shifts. We ty

LASER SOLDERING

Hi Dougs I worked a bit a few years ago with a diode type soldering laser. I found laser soldering very application specific so make sure you send samples off to differnt companies to see actual results. You can get good results with a laser system

Siemens S15/F3 skipping component

(Hey Cal how you doing?) I can't resist this. You can sort of do what you're hoping for but you have to be very careful. Let the component run out and let the machine get as far as it's going to go. Then go to "Software Options", "Test commands" then

If I've been clear, the parts become offset as the XY table moves around, without fiducial correction. It's when it does a fiducial correction that the placement is alright. If the placement is excellent, and I just zip the table around...load posit

Electronics Forum | Mon May 22 15:46:49 EDT 2006 | adlsmt

Grant has a good idea, we started that way also. We made a tank out of stainless steel with copper tube coils about 18" off the bottom. Circulate cold water through the tubes to condense the vapor to keep the loss down. We used electric burners under

Can lead free and non lead free production mix in the same mach

"Can we reuse the same machine? My point here is that the non lead free process has already coated the machine interior ( exhaust, internal flow ) with leaded component, and by conversion to lead free are we containminating the lead free product from
