Hello, We are having issue with one of the customer board. This is 10 layer PCB FR4 with black solder mask. Coating Ni/Au. Soldering leadfree. We are using 7 zones air reflow oven (zones top&bottom). We have bed solder flowing for this boards. T

Jim: Several points: 1 If you�re correct about corrosion of your component leads (which is entirely possible if the leads are steel, as you say), then the AIM 264-5 no-clean may not be aggressive enough to remove the corrosion you are seeing routin

We are looking at an Omni Flow 5 Oven and do not have much information on it. We do know it has a 3" cabinet vent and a 6" vent near the center on the top. If anyone has knowledge of this oven, and has any suggestions or info, we would appreciate

This is from the OmniFlo 5 Engineering data sheet: EXHAUST SPECIFICATIONS: STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unload-end: 300 cfm (510 m3/hr) at the 4� (102 mm) stack (minimum req

Hi, Yes, we just built a new plant, and used copper again. The stuff we cut out of the old building was copper, and it was fine without any issues. We lay it on an angle so condensation flows to an end, and can be periodically vented, and we take a

Assuming you're seeing this during wave solder, the via acts like a heat pipe conducting 450�F [or whatever] air to your solder balls. Check the fine SMTnet Archives for similar threads and perspective on the direction to take.

PS, we had a similar situation when a quick disconnect on the flux supply went bad, limiting flow. Take the nozzle off and turn the fluxer on, you should get a lot of flux flow, If not, the lines are probably clogged.

Grease filters work well. They're cheap, easy to clean and come in all sizes. Will not reduce your air flow by much either.

Definitely too much pressure for any fluxer I've seen. Something must be restricting the flow. Maybe the nozzle.

hello everyone, I have issue with one of my DEK air conditioners, it starts to freeze soon after we turn it on. most probable cause is low air flow or low refrigerant pressure. does anyone know what is operating refrigerant pressure range for DEK ai
