We're a Tier-1 Automotive Supplier, manufacturing here in the Good Ole U S of A, and I'm in the processing of putting together our newest SMT Line. This new line will be a dual lane SMT Line. I've been in the industry a long time, and have put togeth

BGA Rework (Top side heat only!)

Electronics Forum | Sat Mar 28 06:59:03 EDT 2015 | robertwillis

I would agree with the comments so far its much better to have some pre heat. You have not explained why bottom side preheat is a problem. Even having some input will help balance the process. Assume there is some thing on the back side that is a pro

Anyone familiar with leadsmt's LED-1204T

No, I'm not sure you will find anyone outside of China (well maybe Iran). You keep seeing many remarkably similar Chinese machines pushed on forums, eBay etc but I have never encountered anybody saying they had one. Neither have I encountered any equ

Questions you would ask if someone said they had a 3D printer for professional multi-layer PCBs?

Electronics Forum | Thu Feb 26 08:44:38 EST 2015 | spoiltforchoice

...Unless you could dispense a fine glassfibre mesh in much the same way a 3D printer extrudes plastic filament and then spray epoxy over the top. It would be remiss to 2nd guess what compounds physical chemists can come up with for such a project. E

Hi everyone, I just got a GF-12 oven that looks in good shape but it won't go into WORK mode because it needs to run a TUNE. I've read that this happens when the internal backup battery fails or after a specific time. A while back a member posted t

Samsung CP45 File Save Issue

Electronics Forum | Mon Jun 08 21:44:40 EDT 2015 | superlen

Thanks for the feedback and the confirmation that it is, in fact, a bug. I have trained my operators to always use file Save at the end of the day (up to a network drive) & then I have an external program that archives the daily setup back into our r

Advice for a newbie, please: Can an existing PSB be adapted to slow it down? Maybe add a resistor?

Electronics Forum | Thu Aug 06 15:58:20 EDT 2015 | r92024

I'm looking for advice, please, concerning PSB ’s. I’m a complete newbie and not very technically minded, sorry! I manufacture and sell wall clocks that have a swinging pendulum. The pendulum mechanisms are made overseas and designed for the pendulu

If the pendulum is motor driven, it's more likely that a capacitor change will accomplish what you want than a resistor change. You've got a 47uF in there...try a factor of 10, and put a 4.7uF in there and see what happens. If the pendulum period i
