Stacking chips

I need to install two SMD chips (0805) at one location. I refered to IPC-HDBK-001, fIG 6-24. When I solder the chips side by side, the ceramic side which is placed againgst solder pad- is already touching the solder. While I complete the solder joint

bulk feeding chips

I think you just answered a questioned that I never thought to ask. Are bulk parts manufactured differently than standard tape and reel parts? That would explain why there is a bigger price difference in parts from Murata and not from others. As I

Bulk parts cassettes... another idea that must have looked good at the time. Too bad the manufacturing trend went from low mix / high volume to high mix / low volume. I guess the feeders have to be too complex to feed the part properly to the machine

removing glued chips

We find it impossible to remove the glued micro-BGA chips like the CPU and the UEM ICs used in Mobile Phones. They are both surface mount devices and glued with some chemicals we think. Any help is most needed in this matter.

at present we try to do it with hot-air gun adding flux below the chip while heating. but in most cases the PCB gets damaged while doing this. sorry again for late reply.

Hi, Im having problem on tombstone, The part is LF chip component 1005, and my solder paste is WS leded. tombstone is not in a deg angle but one side is soldered but the other side is just sitting on the solder. Looks like my solder can not wick up t

So, to really get reliable pickup rates from new bulk feeders, I just need to replace all the chip shooters we have with more recent ones with pickup correction capability. So where is the saving? ;-) -Upside down resistors? not an issue. so what if

Mounting 0402 chips

Hi We found the misalignment sometime during SMT 0402chips. So, we made the pick up speed a bit slower then the condition was better however it was time-consuming and delay shipment. We r using Yamaha 100Xg SMT M/C and no probelm in mounting 0602 o

Application...oh, we are a high volume, low mix (HVLM). Forgot to answer that one earlier.
