We all know that purity of nitrogen is critical for selective soldering. When it comes to wave solder- how much or what percentage reduction in oxygen is enough to make a difference in 1) at least reducing dross buildup and 2) being anble to cut ba

Yeh but, it's really terrible to conjugate and enter a killer topic and then have forgotten it by the time you need to re-enter it as the subject. Do they do it this way over on the Luke Warm Confusion Forums?

| QFP's are best left the professionals. There are MANY subtle issues with fine pitch lead forming such as critical tool design issues ability to check critical dimensions etc. Unless you want to replow this grown in hopes of getting a promotion or

Ok folk's has anyone used Alpha Metal's UP78 solder paste ? Our place is looking to move to that as the way to go, getting rid of the Hereaus 362's and Alpha 737's of the current set up. My question's are really : how is the printability of the pas

Hi, That's the problem, and in one case it wanted to put 6 reels of 10K resistor, when we only had 10 on the PCB. It really only needed 1 extra feeder, but decided to fill all extra 15 feeders in the bin, so setup is hell. It might think that's a go

Hi, The MYDATA is a very flexible machine, however it's slow as a chip shooter, and really needs Myspeed to work to get as much speed as possible. It's also wasteful to get chip placement speed because you need to repeat feeders of the same componen

Hi, It's both really, and we are doing higher volume of current products, but new products are increasing in component count, mostly passives. We have analog on our products, and this uses a lot of passives, plus each semiconductor needs decoupling

Hi, Yes, what a nightmare! We have sent our designs to MYDATA often, but don't get much result as they are also using myspeed. However Scott B's post is really interesting. Can you let me know how you do that? If there is an easer way to optimize t

Metcal? Really? I tried them, and found them to be lacking in ability for my needs. Soldering anything with a lot of copper resulted in the tip "sticking" to the PCB, and it was very slow to respond when in use. The JBC units might not be cheap, but

Hi, I think I am having a bad MYDATA day. I have tried optimizing our MYDATA for the last time with this crap Myspeed software. It does not give any kind of solution unless it's perfectly happy, and so we have to run the machine again slower than i
