Dennis, Not sure why your so secrative about what machine but I guess it doesn't matter. When you start placing 0402 & 0603 packages the difference between height and width and length gets lost in tolerance. This allows the machine to pass parts t

Why, on occasion, are threads "unclickable"? I've been following Phil the Quality Guy's thread and suddenly I can't open it and the subject is missing.

The mount plane is not the same every time. Our machines are conveyorized and the bottom rail is fixed so the mount plane does change with the board thickness. The stand alone table has a V notch for holding the board with the flat edge on the bottom

Hello! all Will anybody give me advice for missing componets for 0402, 0603 R or C chips? I am not gonna tell you which machine I use, but from my experience, every p&p machine has possibility for missing component after placing 400 or more componen

Let me guess, you are talking about a Siplace S15 or F3. The bearings around the sleeve could be dirty and create too much friction for the little turning motors to rotate the sleeve. What do you mean by parts missing? Are you saying components are

Thank you Stefan for your help! our machine is hs50.you are right we means components are not placed on board.we can found the part around the loctation.i found bearing is dirty.i clean it with threebond.it can work well. but i want to know the rootc

The only part, which could cause component misplacement on the rotary heads of the Siplace machine is the vacuum valve. I don�t know the official name in the part catalog, but I use to name it plunger. The plunger is moved in and out by a miniature s

We are using tin-lead solder. The components could be lead free components, they probably are. I will check the plating on the components and investigate changing it.

There are several smd components in our factory that don't reliably wet to solder during reflow. Paste and placement are good, but the component won't wet reliably. All of the other components on the boards solder fine, but one of these components

You should have no problem using lead-free components with tin-lead solder. Is your reflow oven IR or hot air? If you are using an IR oven and the components are white or light colored, they may not be heating up enough for the solder to flow on
