You could have said "why don't you just flop 'em over twice into the right tray?" lol. Yeah, that's the right way. I was kind of focused on what I had to do here to get two different parts from full trays into two cut-in-half-the-long-way trays sinc

My recommendation is that you send all your question to Mumtaz Y. Bora, Sr. Staff Component Engineer from Kyocera Wireless (mbora@kyocera-wireless.com). She is also a member of the committee that is writing the new specifications for Moisture Sensit

Innovative Drying Co., considered this possibility early in our experiments. The rate of chamber pump-down is not a consideration. However, the selection of the vacuum pump is critical. Avoid oil-sealed pumps at all costs. A poorly maintained oil-tra

gersla: You're correct that carriers of low temperature material will disfigure and become useless at 125*C bake temperatures. The reason you can not find 70*C bake data is: J-STD033B, "4.2.2 Low Temperature Carriers. SMD packages shipped in low tem

You are correct. For the 70 deg. C drying temperature to be effective, the relative humidity must be as near to zero as possible. A pulling a vacuum on the chamber is an inexprensive and reliable way to accomplish this. Contrary to some claims, our e

Nerdyboy don't write no blanking program. Get two extra carriers of the same size and configuration as the low temperature carrier that you want bake at a higher temperature. One of the these extra carriers needs to be high temperature material that

Hi I have solder paste that suppose to be stored to 0 - 10 degree celsius. However due to broken fridge, we decided to stored on -40 degree celsius freezer. Does the solder paste still good to be use? Please help.

If the supplier has prescribed the storage temperature between 0 - 10 degree celsius, then it means that it work effectively if stored in that temperature range.

Just completed doing the evaluation. The reflow looks good. No unreflow observed. Meaning to say the solder pastecan be use right. Thanks.

| Hello all! | Recently we got a problem about the Funtional test. Some boards passed tests by using the auto-fixture(vacuum), but failed by using manual test fixture(need to plug CPU, DIMM etc.). The error symptom is no picture. We doubt it's the pr
