Through hole question - what methods can be used to obtain upflow on multi layer pwbs with huge ground planes. We are using a water soluble flux with a max temp of 220 topside. I am pushing the limits of the flux and hitting 250 topside in an attempt

Hi, ok, I have a bit more info after playing further with the profiling. We are getting close, but we don't have enough top side heat I think. The IR lamps just don't give enough, but we can get better connector that should help. But we have anoth

The New Redesigned Vectra , should fit right into the same price range as most mid-range wavesolder machines offer by most. We are looking to replace a existing Delta Wave and found the pricing about the same.But The upgrade prices can be high for no

Hi, Your right guys, and we turned off the chip wave, and most of the problem went away. It looks much better, and we are getting a slight bridging on a USB connector at the front edge of the PCB and a little adhesion, but not any where as much as w

Hi, We have the Soltec Delta C. It works well, and is very stable. I think the software is a bit simplistic, but it keeps the wave stable, so that's the main thing. It's the timer on the software that I find annoying. It has a warm up time, and yo

Hi Grant, Boy, how do I say this - I might have to agree with Wave Master Larry. (Yeah, yeah - I know; Davef and Dr. Shocker will "burn me" again) "We" also solder large thru-hole connectors on with a selective solder machine. They measure 4 by 8

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema

Hi, I would also be interested in this thread, but our problem has a different twist to it. We have good results from our reflow with Koki no clean paste, however when we pass the boards through the wave solder machine, the flux in that leaves a fog

| My company is looking for higher density for card layout. One suggestion has been locating active components packaged in SOT's and SOIC's on the B-side of the card. This in turn will require wave soldering of the above mentioned components. When I

Hi, Thanks guys for all the suggestions. I am going to check what options we have for top side heating. Do people recommend we get convection for that? Also, we seem limited to 60% in the machine setup, and does anyone know how to run the top lam
