This is a pet peeve of mine. The paste height requirement is generally asked because the customer has no clue about screen printing, but knows to ask this question. If he did know even a little about printing, he�d ask you to assure the �volume� of

Let�s not get drawn into making more of the amount of training required in order to be able to develop an effective reflow recipe than is necessary. A low-skilled operator with about one hour's training can setup the solder reflow oven. Consider co

Hi, It sounds like your a little new at profiling, and can be difficult to do well. We purchased a KIC profiler that has software that will take your profile data and tell you the best oven temperature settings and conveyer speed to use. You need

Hi Mike, I haven't tried the 0201s with a Hyrda, but after seeing 20 reviews of your message without a response, I'll try and share my experience with 0402s on a non-Hydra machine. The 0402s are slow, but I managed to get some speed by maxing out

Hi All, The change over to lead-free is as easy or as difficult as you want to make it The big problem I see with this lead-free transition is that there is no benchmark of acceptability and no defect data (yet) related to visual appearance of a sol

There is learning on all brands requiring fine tuning the test parameters. The first point is not to allow defects to escape. Many brands can do a good job with preventing escapes. The struggle with all the brands becomes false calls. The companies r

Our machines can't use 'cad data' for fids. I'm intimately familiar with these machines as I've been using them for 11 years. Most likely, it's a limitation of our machines/software, whereby it requires symetrical local fids. When we place a PCB on t

Hi Patrick, I agree, there've been many anomolies this Winter. I've spent the last 6 months at my company's Chicago branch, and temperatures throughout December were very comparable to the desert heat of Riyadh! I hate Al Gore, the guy's a total to

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part

I am looking for data on the yield of printed circuit board assemblies so that I can judge if our SMT line is performing up to typical industry standards. Following I will describe the details of the assembly and what our yield has been. Each board
