The first time I was faced with this it was on a night shift training M ?????????? and we used a standard hot air rework system with no under board heating. The trick is to keep the air flow low and you can remove the parts. Most people use too highe

The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.

Q1) How to identify on good or bad RF shield that could contribute to dewetting? A1) We use Alloy 770 and 752 [German silver] for our RF shields. We have never seen a solderability issue, even aged stock solders well. * Nickel Alloy 752, Nickel Silv

I work for an electronics manufacture. Our end product is on PCBAs. My question is related to the use of safety glasses, which I know are required when doing rework. But here is the question: We ordered side shields for prescription glasses. Wha

I have read in some magazine articles that there is poor signal to noise ratio of RF devices when no-cean solder is used. The frequecies used exceed one Mhz? Is this true?

We're looking for a contractor who can support high volume production of 0201 passives and 1-2mm csp's to create 4mm sq. RF modules as well as mold cap capabilities. Any leads would appreciated.

I had a customer like this too. Originally, the customer print called for manual soldering of the RF shield (which took us about 20 min. per shield to hand solder), but I changed it to Solder Reflow (I cut apertures on the stencil), with brass weigh

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Hey, I thought you were in the BIG house on some trumped-up tax rap. We use many RF shields each month. Generally, the shields are not plated and made of alloy 770 (or alloy 752), half hard temper, as the base material. * Alloy 770; 55%Cu, 27%Zn,

Hi All, I would like to get some advice from users who place rfshields pre-reflow and reflow onto board. We ran a batch a few months back and boards which had the shields reflowed failed to function properly ~ I was happy enough that the profile
