Has anybody else had issues with shipping circuit boards in static shield bubble bags? It appears that parts are getting ripped off during shipping. I suspect that they're getting caught in the bubbles when the boards shift in the bags as the boxes

we encounter bubbles on silicone coating after oven curing.what to do to avoid bubbles?

1.The bubbles appear only after the oven curing.before curing no bubbles encounterred. 2.The bubbles were very small, and can be found around the die in between the die and the epoxy. 3.Curing time is 150 degC for 4 hours.

I am having trouble with little air bubbles in my conformal coat. It ranges from a few pin sized bubble to looking like spit. We are using Dow 2620 silicone conformal coat applied with a PVA sprayer machine. The conformal coat comes in bladder bags t

I have found that depressurizing the tanks when the machine is not in use reduces bubbles.

Are these molten solder bubbles, or another substance "foaming" up on the surface?

I am using Humiseal 1B31 conformal coating and xylene mix on a PVA coating machine. Bubbles are appearing between the pins of LCCs mainly and bubbling is worse when put through the IR oven. Does anyone have any suggestions or tips to elliminate this

Hi All, Recently we are working on the conformal coating process using Humiseal chemical 1B73 and thinner 521. Bubbles on component body/joints are seen after gone through the IR Reflow Oven. During the conformal coating, only tiny bubbles seen af
