| | I am finding that some of our IC's are coming from the supplier with the humidity gauge in the bag reading 10-20%. Has anybody done any tests to determine what humidty level in a package will cause problems during reflow? | Usually a proper m

Humidity card should show actual humidity in the package accurately. If it shows below 10%, actual humidity should be less than 10%. There is nothing to account for from previous cards.

I have a question about Humidity Indicator Cards (HIC) in sealed PCB packages. If a PCB package is temporarily opened where the HIC card indicates 20% humidity exposure and then the PCB package is resealed with a new HIC card. How is the 20% moisture

Hi Peter, I read your concerns regarding IC parts not packaged with desiccants and thought you may find our new Type 2 Humidity Indicator card of interest. Please visit https://www.clariant.com/type-2-humidity-indicator-card Thanks, Elsa

The humidity card must reflect the precise level of humidity present in the shipping container. If the reading is less than 10%, then the relative humidity is less than 10%.

The indicator cards only show the current humidity, not the peak. They will revert back to blue if placed in dry conditions.

Here's what Desco says ... Humidity Indicator Card (HIC) A card on which a moisture-sensitive chemical is printed such that it will change color from blue to pink when the indicated relative humidity is exceeded. This is packed inside the moisture-se

Repairing these PCBs was not an option due to the delivery amount. Oxidation is unlikely, as these anomalies were visible right after unpacking them and the humidity card was not suspicious. We have since decided not to use these PCBs as the risks w

1)What is the MSD level for PCB? 2)I have some PCB's with HIC (humidity indicator card ) has turn to pink at 50%. Should I bake the PCB prior to assembly process.This fab is a complex board with various kind advance package assembled on the board.

One of our aerospace customers "suggested" we vacuum seal MSD components. We bought a vacuum sealer and we are deciding whether or not to vacuum seal ALL MSD parts or just aerospace. Our current method consist of desiccant, a humidity card and a bag
