Russ: That�s a pretty stand-up postin� bud. It�s neat that you can root-out that dirt. We couldn�t dig-up that stuff, if they threatened to shoot the dog. You could be correct about using convex for waving. We don�t wave RNET as Philips suggests

Just wanted to add a few comments on the discussion of how to identify palladium parts. Generally, there is no "clear-cut" way to identify Pd versus Sn/Pb. It mainly comes with experience. Any part that is is plated prior to being trim/formed will

I have a QFP 160 used on 9 different products that had high fall out for "Insufficient Solder". Basically, a leg or two would pop free when inspected occasionally. This same part is used on different size products, located at different area of each

I agree with prior postings, but there is no perfect yes/no answers, right (left)...? Only good questions to be answered. I think it is overkill to have an extra stencil, why do you need it? (That is if you have a proper stencil cleaning equipment).

d0mino, Given the fact that the SLIMKic has built in wave detection, you can just make a pallet out of 10mm delmat material, and drill a couple of holes on the pallet for the wave detect T/C's (ports 2 & 3 for left and right). All the wavesurfer is

Hi Yngwie Have you got a reflow oven yet. If not, forget about complicated profiling with test runs or reflow trackers. We've got a nice oven with integrated temperature-feedback system. You build any profile you want and the oven will adjust its hea

Hi, I currently work on SMT department to uptimize all process. I've just selected the solder paste after testing 15 different products. To be able to do that, I had to create a procedure to evaluate each paste and to be sure that my profil was per

We recommend a ramp soak spike profile for HASL finish, so everything gets nicely heated during reflow, we soak around 180C and peak at 245- 250C and don't have any issues as long as the levelling isn't too peaky.

Russ, The caps are 0603 case size. I am not sure about the manufacturing details, as I work for the capacitor supplier. The manufacturing details are unclear at the moment, as the customer (South of the border) has not released such detailed inform
