Much ado about nothing. Reminding has failed? Who runs the place? You sound like you are a person in authority. You may not be the boss, but authority has weight. The folks that can't seem to remember (or care to remember) have bosses that you c

All, I would like to find out if it is possible to adjust the cooling rate on a Conceptronic Reflow Oven Model HVN70. We do not use Nitrogen and the Cooloing system is Genesis GCM-1. From profiling it seems to be cooling too quickly. Any replies a

Was wondering if anybody has experience a zone that will not get up to temperature. I changed the Solid state relay, made sure the thermocouple is working. The only thing I can think of is the bottom heater panel has a corroded/broken wire which is a

Hi Indy, Check http://www.jmw-inc.com (they are in the midwest so shipping will not be too bad going out east). I bought 2 MPM printers and a pick and place machine from them late in 2004. I know they have 5-zone reflow and 7-zone ovens there (elect

Are your preheaters maxed out then? What is conveyor speed? anyway I would not have issue with that configuration at all. I have actually found that when using convection for some watersolubles you actually dry out flux and performance is worse.

Water soluble pastes generally work best with a ramp-to-spike reflow profile. Check your paste manufacturer's recommended profile. There are many factors that impact your profile; board thickness, component density, buried thermal masses, board si

Try a linear, very flat ramp rate on the order of 0.5 degrees celcius per second. I know this is hard to accomplish with a five zone, but try to lower the first couple of zones (the preheat zone), and then spike to reflow aggressively during your la

We are parting out a GSM2 machine and plan to keep most of the parts for spares but if there is some bracket, bearing, roller, switch, etc. that someone needs let me know asap and we'll see if we have it.
