I've seen them down at 2 metres in the past, but usually only 4 zone. from memory Electrovert used to do a small 5 zone with pin chain - Infraflow 500 or something. To be fair, even small one line CEMs usually have a decent oven as you need to be a

Ken, The technology you are referring to is also known as return-to-web. This panelization method involves a hard tooled perimeter die and a press equipped with an air cushion. The PCB circuit is punched out and then inserted or "pushed" back into

Hi, We are using mixed technology in our PCBA. Would like to know whether there is any criteria governing/guiding the use of mixed technology in such aspects as: 1. Some SMDs cannot be used in some kind of PCB materials such as FR1? 2. Some SMDs are

| | Thank for the input. But I guess I was looking for more. We have been transferring boards for some time and a have good working relationship with our primary CEM and have worked out many bugs. I was thinking more on the order and don't shoot m

We have an electronic circuit with a miniature stepper motor, quartz crystal, Electrolytic capacitor,chip resistors and few smt LEDs. The PCB material is CEM1 with SMOBC and HALS finish. This circuit is assembled in a plastic casing and goes in to a

In most cases PnP files are all that is needed for SMT program generation. BUT, it depends on origin reference of this data as exported to PnP and could be off in X,Y and rotation of image pending when PnP Data is exported. Also Rotation of parts

OK, well as a small CEM I've dabbled in this area because when you are small you end up doing some of this work in house without specialist web knowledge. This frankly isn't easy, as you are selling a service rather than a physical product and hundr
