We have two QUAD 4C working in tandem. 3 months ago the EPCU battery (QUAD # 2) died, then we change it. Then downloaded the MODs from the controller to the assembler(does simultaneously on both machines). All this time we continue to work normally.

It sounds like your dispenser has a problem....The default mod code for 56 is 0 (this should be off). Thats why when you cleared the mod codes the machine was able to home. When you reload your saved mod codes it is probably set to 1. The machine wil

I have used the 850's previous version (and other batch ovens). The current specified was AFTER the unit was at operating temperature, not what it took to warm up. If you have power restrictions, like I do, be careful with this model. Having used ba

Same idea but simpler execution. Verify Solder pot temperature. Verify Temperature of Solder as it leaves the nozzle. Verify preheating gets your PWB up to 90C-120C prior to soldering. Check machine speed, verify 4 seconds contact with solder at

There is a method and let me stress that you need a competent wrench man to do this.It does require a "crows foot" jig that you can probably get from a used equipment dealer. The proper way to clean the clutches is to remove them from the ring gear.

There is no 8mm wrenches involved. The procedure is a little to extensive to post.The only hand tools required are the crows foot jig a set of allen wrenches and an adjustable wrench. You have to remove the shaft crown to get the clutch out. Again..

We use JBC here. I like the response time of the iron tip. When soldering, the tip temperature does not drop as much as the Weller's we used to use. I like the ease of changing tip sizes. I dislike the cost of replacement elements. The tip and

JBC is a great performer, but tips can get a bit expensive. If you are working smaller parts like 0402 and 0201 capacitors, go with the JBC Nano Station. We have 3 stations, each with dual Nano soldering irons. The balance of our stuff is H*kko Fo

I am not sure what the IPC spec is suggesting....K type thermocouples are normally specified upto 1250 C, of course there is a tolerance in their accuracy and this probably degrades after hundreds of uses through a reflow oven, but normally the accur

We are thinking of getting a small pcb assembly setup for a small manufacturing co-op here in Los Angeles. Our experience consist of manual soldering of through hole and smt components. A quick search suggests that there are a few turn key opt
