We're unfamiliar with such component dryout requirements. Commonly, tape & reel cover tape will seperate at 60*C. So, even if your baking on a metal reel, your should keep the bake temperature ~40*C. Sure makes you want to use these parts during th

I have two cases where I must bake after DI wash. The moisture entrapment is specifically within microprocessor sockets. Without air gun blow out and baking, oxidation occurs that causes flaky contacts for the PGA. We will bake for 2-3 hours @ 60C. O

What is the correct method to bake or cure the component?Standard baking practise by us is to place the units into oven at 125 �C for 8 hrs directly. But I was told that the correct baking practise is to cool down the Baking Oven to Room temp and onl

I have never heard about a requirement for temperature ramp-up for baking components at 125C. In general the concern for delamination with moisture sensitive components starts above 200C (peak body temp). Most important is you should bake your com

We are going to be placing BGAs for the first time, and I have some questions. Is it recommended top bake all of the boards and all of the BGAs before production? I have had good luck baking boards that didn't wave solder well. It usually turns out

A baking oven over 100 C will be at zero humidity. Do you really need to store pcbs/devices at 200 C...this will surely harm some products ? IPC 33B01 allows storage of MSDs in a dry cabinet at less then 5%.....these can operate at room temp or 40 /

You're correct 45� is preferred. 5 Paste sticking to squeegee: * Squeegee is heavily magnetized * Some pastes stick more than ... * Plastic squeegees stick more than metal * Old metal squeegees stick more than new * Paste needs to be worke

The current IPC/JEDEC standard J-STD-033 for moisture-sensitive devices does not include a bake cycle at 90C (it includes cycles at 40C and 125C for non-assembled components in reels or trays). However, the upcoming revision, which should be release
