Temp/Humidity requirement for baking normally specified at : Low Temp baking : 40 deg C at 5% RH High temp Baking: 125 Deg C at 5% RH. The problem here is the 5% ? Although the 5% is achievable with a special Oven, can someone explain why is it 5%

Dears, Could somebody advice is there exist requirements for storing(like humidity , temperature, etc) for PCBA (PCB with SMT components)

I'm not aware of a standard for the storage conditions of assemble circuit boards. Here's what I'd do: * Protect them from damage * Store them vertically * Constant Temperature 22°C +/- 3°C * Humidity Control 45% To 65% R.H.

There are two similar products, Eureka and McDry dry box units and other nitrogen required units in the market. Both Eureka and McDry are not required Nitrogen, I'm seeing a cost saving there in the long run. I have several Eureka dry box in the faci

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

Hi folks, I was wondering what the combined wisdom was on the humidity effect on the MSD control required by the Jedec std. The std works on a relative humidity of 65%, if my RH is only say 30% because of factory environments how do I easily factor

Table 4-1 only specs the humidity requirement for bake temperatures below 100C. It is conspicuously absent above that. I believe it is because moisture is in its gaseous state above 100C.
