Hi, We are encountering a shortage on our parts and our purchasing said that the parts, which is in PLCC packaging, is hard to order from the local and international market and we can only get them in QFP packaging. Now the problem enters here. Our P

Use caution if epoxy is dispensed under the PLCC 84. If the "SMT Gods" look unfavorably onto you rework will be difficult. I had a ceramic PLCC 84 which weighed 15 grams (MCM) and due to packaging failures (glass seal to metal cover) rework was the

Hi guys; There are a few points that should be taken in to considerations regarding IPC-SM-782 land pattern and design rules. As a general rule all SMT reflow pattern should be in comply with SM-782 but however for special cases like : * PLCC land

| Can plcc's be glue on the a board if not why? | Ron, The biggest problem you have with PLCC's is the hieght of the base of the component from the board, if you can get a glue dot high enough then yes you could do it. Probably the best method is d

| We might be doing a job with some plcc, soic on one side and the other side will have two BGA's. Does any one have any ideas on what knid of problems that might occur if we reflowed both sides? Like heat temp, surface tension, etc. Thanks for any h

I love these stories. At my previous employer we experienced intermittent failures on an audio microprocessor assembly being used on a *new* product. This board had numerous microprocessors and complex firmware aboard. They discovered one PLCC on

2, I have to scroll down to the bottom to see the image... and the outline of the legs isn't very clear. The legs are sort of blurred together. I had tried lowering the CCD offset in the part definition to -50, but it still looked bad. Could this

This probably won't help much but I find it at least a little interesting. During some experimentation recently I accidently loaded a board into the wave upside down and it had a PLCC 68 package along with other types of components that had only bee
