Conformal coating Mask for connector

Electronics Forum | Fri Feb 20 17:04:26 EST 2004 | Long

Hi I am looking for some type of peelable mask or plug to cover the connector during the conformal coating. The problem we have is the moisture get into system and eventually penetrate under the connector creating short circuit to the board. What I r

Anyone use glass filled nylon connectors utilising the intrusive reflow techique (pin in paste). We are having probe with them becoming brittle after reflow- apparently due to moisture. We are also seeing bubbling on outside plastic.Peak oven temp 22

Marc, There are many types of nylon used in the connector industry and some are designed to be used in high temperature (225-250C) oven reflow applications. These high temp nylons are usually types 4/6 and 6T. It sounds like you are either using a

You need a nylon with a heat deflection temperature [heat distortion temperature] - 0.45MPa ( C ) similar to your reflow peak. The HDT of the nylon in your connector is probably ~200*C. For more, look here http://www.tycoelectronics.com/environment

We use HTN (high temperature nylon - Zytel) connectors in our reflow ovens with no warping, bubbling, or cracking. You can also use PPA (Amodel).

Interested in pin-in-paste process with standard ROHS connectors

Thanks. Yes, we have attempted to use standard ROHS profiles in the past and turned our THT connectors into 'chucky dolls' after the PCBA left the oven. We then realized that we need the high temp nylon connectors to allow for the use inside the SMT

Do you need to bake after parts are in the Dry Cabinet

Electronics Forum | Wed Feb 01 11:47:07 EST 2006 | Mike

James, If you have a true MSD issue, then baking them AFTER your reflow is not going to fix the issue. I would have to agree with GS and look at trapped cleaner media (if your not No-clean) under the components, or inside connectors. If your runnin

As we understand it, you: * Get some nice BGA from your supplier * Find BGA to be packaged properly * Bake the BGA for 24 hours at [what temperature?] to reduce the potntial for damaging moisture sensitive components during following processes * Remo

THIEVING * Layout: I�d guess the surface area of your thieves is not large enough. The pull from the thief is not great enough to over-come the pull from the connector pins and pads. Consider tripling the size of the thief. As you say, reducing t
