Hi, If your PCB is large, you waste a time. Any picture, you takes, will be with corner distortion. I suggest you to: 1. use AOI (manually or automatically) 2. try simulation of your PCB production before real SMT production process 3. use human FAI

Does any expert here know the specification of board deflection when we mounting component by pick and place machine? That is when the nozzle place the chip on the pcb, the board will have some deflection. And are there any requirment that we need t

I did not buy this machine from Contact, therefore they will not support it...unless you buy the 2nd user support package I think its called. I think a lot of people ask questions about Contact because there are so many used machines out there.

Is there a reason why you want to wash the board before wave?!?!? What is your process flow? I run bottom side of my boards first, then top just to make it easier to setup (easier to put those support pins around those smaller components). But,

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in

"Too Hot" is any more heat than what is needed to reflow the solder. You should have the Auto-Profile software for the machine, this will accurately monitor and record temps. There is also port for the component itself to monitor package temp. There

I am looking for a service providing non contact PCB flatness measurement for open board SiP assembly. It was returned for failure analysis with complaint that assembly does not solder properly onto customer system board. Since there are remnants o

| | I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the a
