Here is what you need to do if you can, Since you want to shporten the bake time you need to increase temp. weigh a board prior to your current bake process (you need very hi resolution scale for this) weigh the same board after current process a

You may very well be right Hussman, but I'm not certain that marcin knows exactly what he wants to know. :) I would call that ramp rate, not delta t, but that's my language. marcin, what I'm talking about are the varying temperatures on your board d

We've got lots of connectors at my place of employment like this. What I do is... I run these "slower than molasses in January" - we're talkin' 2 Ft/Min. conveyor speeds. Obviously this will have an effect on your thermal profile so compensate acco

ET, With due regards to your '7 years experience', I must say that in my 11 years experience, this is the first time I am hearing about head replacement on a Topaz. On the Eclipse it is easy for an operator to make a mistake by moving the head manua

Here are the differences (Eclipse vs Eclipse II) Optimum Speed: 5000 vs 6500cph Feeder Positions (8mm) : 80 vs 94 PCB Loading Time : 4s vs 5.3s PCB Thickness : 0.6-3mm vs 0.5-4mm Max Component Size : 32mm vs 45mm (optional camera possible on Eclipse

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre

CK, If the contact length with the wave is decreasing when decreasing the conveyer speed and visa versa you need to check the machines electrical or electronics something is very wrong. Contact length is determent by wave design, wave height, convey

The only easy solution is not to handle the boards. Purchase true double sided reflow lines. Buy automated magazine loading conveyors. Check machine board supposrts. Are you sure it's from handling? We found it was 50/50 between board handling
