PTH crystal is malfunction when humidity is up to 90%

Electronics Forum | Tue Jul 06 08:48:11 EDT 2010 | Sean

Hi all, Is anyone used to encounter PTH(plated through hole) crystal component(Not SMT component) become malfunction when the environment humidity is more than 90%? It is happening here...It is very weird that crystal become OK when humidity is bac

Bubbles on solder joint(after conformal coating curing)

Hi Ju Yong, The PCB are dry in an airseal cabinet(Staging Chamber) before IR Oven. The bubbles show at around body and solder joint area. You mean the moisture will create bubbles ? Able to advice the humidity and temperature that you are using in

WE USE 3 chamber OF Mc-DRY(MODEL NAME). THE MACHINE CAN REMOVE HUMIDITY FROM PARTS IN THE GENERAL PERIPHERAL TEMPERATURE (MAY BE 25-30;CENTIGRADE). AND IT'S CONVENIENT FOR MAN TO PUT OR TAKE OUT COMPANENT FROM CHAMBER BECAUSE THERE IS NO HOT AIR AN

Baking MSL components in vacuum.

Hi, "Baker with controlled humidity 5%" is actually dry cabinet. Using of dry cabinets i.e. ambient temperature baking is preferred. Vacuum will always be better. If you are going to use vacuum chamber, that will be the best method in my opinion.

Currently use Hysol TS300 latex mask and need to explore alternative methods of drying the mask. The mask is applied with a Asymtek Century Dispenser and placed on drying shelves. Air dry is dependent on temperature/humidity. Tried all the UV masks o

Baking components at 70 degree

Electronics Forum | Tue Jun 17 12:57:26 EDT 2008 | sleech

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

Baking Components @ <5% RH Is this Really Needed?

Electronics Forum | Tue Aug 13 16:43:28 EDT 2024 | rwyman

Hi Armando- You don't need a "Humidity-controlled oven" to achieve <5%RH in your baking process. I have (3) Grieve 333 ovens that are used for various bakeout/drying processes. All get their make-up air out of the room they sit in. I ca

Resonator Cracking

Electronics Forum | Fri Nov 16 08:47:04 EST 2007 | rgduval

Fractured parts that we've seen at reflow in the past are related to trapped moisture in the part, out-gassing at temp, and fracturing the part. I have seen this on ceramic resonators in the past; don't know why this type of part seems prone to this
