This one's got me stumped, so I thought I'd throw it out for discussion: I have a 20 pin SMT ribbon connector by Molex that I've been using for about a year without problem, but recently things aren't looking so good. The solder is pulled up off of

Minor problem with rejected parts on a GSM C4 single flex head. UIC support was helpfull but I thought some of you may have encountered this problem and know what's the matter. We are rejecting 1 out of 3 SOT-63 parts. The problem is occuring to part

I think we should shift this issue to the machine suppliers, requesting changes in the machine design, in order to keep at least the jobs of high mix, low volume in this country. We can only compete with low labor cost countries by increasing the lev

Hi Rob we had Electroverts and the cost to convert them was just crazy and the nozzles and specification would never have really be able to run leadfree as for life of the machine, I was able to see the machines running some for had been running 24/7

Patric, The product is exempted from the RoHS regulativ 1'st phase(2010) and our policy is to follow the new EU regulations as this will also push the Industri technolegy and the SMT process. Our concern is more that we are not able to qualify the p

Hi Vickt, Future upgrades on machine software should be free when they fix known bugs/problems. However these are usually sold as upgrades with additional benefits thrown in. That's just hiding the fact there was a problem in the first place, an

Don't have any graphics but they are relatively simple. 1. They do need to be put into the copper. 2. We usually use a 1mm circle but many other shapes and sizes are useable but I know that all machine will take a circle. 3. Maintain a keepout area

I've been using Xilinx TQFP's in the 44 and 144 lead sizes with no trouble. I don't even bake them before reflow and have never had any problem. The Xilinx parts are certainly NOT sensitive, I could not break one with my bare hands if I tried (I ha

I have worked on many platforms over the past 20+ years of being in SMT, before that it was thru hole so I go back to the late 70's in this line of work. Some manufacturers I have worked with have been Quad,Fuji,Amistar,Sanyo and Universal. Of those,
