How AUTO Insertion Machine axial component insertion Head works for PCBA

Low Parts Count: Once the Low Parts sensor is made (parts are not detected) the machine counts insertions for the head that is low on parts. When the count is reached the machine stops with an error code indicating it is low on parts. If the sensor detects parts before the machine stops, the counter is reset. If no Low Parts sensor is mounted, this field is not used and the default is zero.

What is a Printed Circuit Board

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductivesubstrate. Advanced PCB's may contain components - capacitors, resistors or active devices - embedded in the substrate.

How to Design a Printed Circuit Board

Printed circuit board artwork generation was initially a fully manual process done on clear mylar sheets at a scale of usually 2 or 4 times the desired size. The schematic diagram was first converted into a layout of components pin pads, then traces were routed to provide the required interconnections.

Engineering Process before Manufacturing

Manufacturers never use the Gerber or Excellon files directly on their equipment, but always read them into their CAM system. PCB's cannot be manufactured professionally without CAM system. The PCB CAM system performs the following functions:

Patterning of Printed Circuit Board

In subtractive methods the unwanted copper is removed to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced.
