I am having an issue with our CP-642. It will place fine a great deal of the time however when there is a feeder issue or if the cycle changes, after a part is replenished, it will suddenly miss RS1A diodes on the boards for about five to ten boards

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow

Rob, 1) I have not yet tried treating each side as a large lead. Thats an excellent idea and I will give that a try shortly here. 2) I have skipped the coplanarity check in attempt to get it to place so it is failing the basic version. 3) we are u

Hi Dave, Thanks for the suggestions. To clarify a couple of the points... - What do you qualify as "small" & "large" parts? - Do not make the pad narrower than the lead width. The nominal or the maximum? If I use the maximum width I'll be back to s

Hi all. One of our customers recently asked us during an audit of our PCBA rework line if we have a limit for the total number of reworks/repairs that can be done on one PCBA. We specify 3x maximum on one location of a major part (LSI for example). B

Depending on your D.I. system, your maximum temperature concern may be at what temperture it returns to your D.I. system. Hot water may foul you set-up very quickly. As for maximum tempertures for parts, your biggest concern should be drier section

"small" versus "LARGE" parts? Jeez, what do I know? We don�t have a formal definition. They�re the ones that make you say: �Now, that�s a BIG-ass part!!!� �nominal� versus �maximum�? Yes, yer correct.

hi guys the scenario is: when placing parts which required maximum speed, the cp6 sometimes missing resistors here and there, when checking part data, everything ok i notice that when the machine switching between high and low transport speed, (eg: r

I agree with lucky that there are fields to watch wich will improve optimization but still to get maximum throughput you may have to manipulate a little. One thing that might help is to be sure that "consider part height" is not selected, this will e

Is there a spec for the adhesives used to hold down parts before wave soldering. What size dots are recommended and what is the maximum shear force(1LB?) tested for to ensure good adhesion. Your help is appreciated Rich Scheleski
