Thanks for taking ur time to answer this. =) The pick and place machine is just pick from wafer(on tape) and place into waffle pack. I read from some of the sources saying that the ejecting needle and the vacuum pick up bits could cause the die to c

You might find a lot of experience in the forum here, but maybe not so many consultants for this niche. BGA underfill is not rocket science, and in my opinion, the key items are the material chracteristics, and the dispensing method and pattern. Fo

We've got a Novastar 12S wave solder machine and we've been using Kester 951 flux for years with no problems. We just got a new bottle of 951 and it does not foam correctly (thin foam with lots of large bubbles). After a lot of back and forth with

I would like some input on reworking BGA's and the best method. I have reworked BGA's since 1998 using both micro stencils and just flux dipping the parts. I have reworked SN/PB and lead-free (AIM NC258) BGA's for the last 8 yrs. with just flux. I ha

Hi all, We just got this machine and it is not fully functional. I read somewhere here that the folder mint has some useful stuff. I run mint and it said that it cannot communicate with card 0,1,2,3 (x1,x2,x3,x4). It said to make sure the cards are

A big customer for controller cards is complaining about the quality of the soldering on our PCBs. The photographs they sent were very unreasonable, pointing out minor defects such as tiny (tiny as in smaller than the point of a pin) drips of solder

So you are saying that building to class III is going to prevent failures? I disagree. Class III is trying to hit target condition in every aspect of the production of the circuit board. That my friend does not ensure failures from happening. I see

Now I see - not sure. The only trouble I've had that was similar was because an electronic eye on one of the stages was seeing a machine that was installed a couple inches over the top of the conveyor. We had to install a flat black plate on the ma

We'd like to help you, but we don't have a clue of what you're talking about. * Which 'heatseal' machine are you using? Is that a reflow soldering machine? See, we think of a heatsealing machine as one that bond the two sides of a plastic bag togethe

Our company would like to be able to inspect 0201 parts using our YesTech YTV 2050. To do this, we have purchased a doubling lens from YesTech that attaches to our top camera. The problem is, we bought our YesTech used from another CM, not from Yes
