Bright ideas??? Bright ideas!!! I got bright ideas. In order of decreasing luminosity: * Stop installing the socket, solder the PLCC to the board, dip the board. The socket is a waste of time and money. You never replace the PLCC in the field, a

Chris, With thanks to Eyal, this is Graham Naisbitt (NiceBit? - Talk to Eyal later!) We can indeed offer you semi-automatic equipment from around $8K US. Your budget is really low, we have to make a living too you know. However, this equipment do

Most LCD manuf. specify not to wave or reflow. I believe this is because of the prolonged exposure to the preheat temp. However, about three years ago, we were running about 350/wk of a 40P DIP LCD through the wave with no fallout. It did stress t

Never heard of N-Tech. Whose material do they use? Two common materials are: Imidazole (Via Systems) and Entek (Enthone) OSP is a lacquer that fabs apply to boards by either spraying or dipping. What thickness control does your fab use? For inst

Have a project that use to have them. End up getting a little grayer every time they came around. Finally got the design Engineer to redesign the board with through holes. Now the part is used the way it was intended to be! Ended up costing us more m

Electroplating [electrolytic] and dipping [HASL] are the two methods for applying solder coatings to features on boards. Disadvantages of electroplating lead / tin are: * "Weak knees" created at the edge of plated through holes. [I used to get weak k

Our mother company shipped to us a lot of old datecode material and upon running them in the line we experienced non-wetting condition, esplly on the 0402 ( not tombstone ) We have run a dip-and-look test but I guess the method is very subjective as

I am looking at the Pump application for several bottom side applications we have. They are heavy in through hole radial and dip content. The initial testing of the stencil was very good, but I am concerned with inspection of the glue. We do a sampli

If you've told your experts in Germany and US as little as you've told us, I'm not surprised they don't know dip. Sorry, I just snapped there for a moment. That wasn't politic, was it? Yes, it is possible that the other solder connection on this c

Back to Wolfgang's original request. Stacking chip components is just one of many unusual mods that are being added to IPC 7711 Rework of Electronic Assemblies. While some may deem this technique unacceptable, it is a relatively common practices
