If I couldn't afford to go to Boston to get some training from the seller, I certainly can't afford a week in Australia! But, thanks for the offer. I do have the HHK (hand held keypad, that's what Philips calls it.) And, after tinkering with var

I'm in the high reliability (exempt) sector and have thermal cycled hundreds of boards in the past few years. As far as which is more reliable, SnPb or SAC305, my data is similar to what the technical literature is saying, "It Depends". In low stra

Oh no! Doom and gloom on the horizon! Why should I even try? Gawd, I've heard this sh@t all my life and ya know what? I went to school, got good grades, worked my ass off, landed a decent job, and still work for a low IQ, non-Chinese, non-Indian

Hi there CK, I didn't follow the link yet, but I thought I'd comment on your post here. I've attended two engineering schools in the USA, and one of them was a pretty darn good school. At both, I would have to say about 80%+ of the graduate studen

Wow, you're using the Surface Mount Adhesive for mechanical vibration? I've never heard of SMT adhesive being used for things other than holding the components in place before wave solder. Does it work for mechanical purposes? Glue/Wave is a proce

In the infamous words of one of my good customers. "Vision systems suck, it's just that some suck less than others" and he would know having hand built AOI systems internally for over 10 years. Do you have any idea how many people think one-off mac

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve

I am still learning the CSM84, but have gotten one board programmed and working. Now, I'm doing the next board, and need to use the mechanical alignment unit for a 22 x 22 mm TQFP. This chip is too large to clear the jaws on any head. Can the CSM h
