Quad IVc limit error

Electronics Forum | Fri Apr 08 21:39:17 EDT 2011 | jimlas53

Hi, We have a Quad IVc set up with all picks, placements, and sequence working. I have managed to get through several passes with some pain, mainly from SOT-23 parts, but it is getting better. On occasion, when picking from one of three feeders loc

Hi, Besides the 2 machines mentioned which are part comparison machines that require the operator to provide a pass/fail on each ref id, there is a system called the FA Inspector which offers the mode described above and two additional modes: 1. Au

I have a very odd problem with my Fuji IP3 and was wondering if anyone can help. Any part that gets picked from the MTU will fail vision recognition. After turning on the vision trace data, I can see that the IP3 is looking for the part to be rotat

Trouble selective soldering fine pitch connectors

Electronics Forum | Mon Dec 10 13:26:40 EST 2012 | dyoungquist

We are using our selective solder machine to solder a backplane with sixteen (16) 4x48 pin 0.080" connectors. Our first pass yield is about 85% meaning that 85% of the connectors come out with no bridges. Not quite as fine pitch as your connector a

My company is starting to look into Conformal Coating Equipment. From preliminary talks it sounds like we would like to use a UV material. I have a few question I was hoping as a group you all would be able to pass along some insight. 1. Do any of

Vapor Degreasing, Inline Aqueous or Batch Cleaning - What is your preference and why?

Electronics Forum | Wed Aug 14 10:44:04 EDT 2013 | sarason

In my limited experience. A Domestic Dishwasher with no water recycling like which is offered on some of the newer high priced models works a treat. Clearly this is batch. Inline filtering of the water supply is a good ideal. There are several ways o

Using an AOI for TH solder checks

Electronics Forum | Mon Aug 05 08:48:10 EDT 2013 | simplycomplex85

Our model of machine does not do "blob analysis" so I'm not sure what you mean by that. "Pattern matching" will only pass if I set the pass percentage down to about 45% and I don't feel comfortable with that. When using a solder inspection everything

Using an AOI for TH solder checks

Electronics Forum | Wed Aug 07 15:41:28 EDT 2013 | simplycomplex85

Absence of solder is just black/super dark red which still falls under any percent I could put in there. So it passes. Maybe I'm a bit confused on how the machine checks solder in general anyway... 0%-60% is a pass by default. Thats anything dark - s

We are a very small EMS that has been sued by a large OEM customer. We built a board, it passed the customer supplied tester, but we had accidentally put a wrong part on it. This was discovered years after we had been placing this part. The cust
