Automatic FPC Laser Cutting-Laser PCB Depaneling Solutions Description

PCB depaneling (singulation) laser machines and systems have been gaining popularity over recent years. Mechanical depanaling/singulation is done with routing, die cutting, and dicing saw methods. However, as the boards get smaller, thinner, flexible, and more sophisticated, those methods produce even more exaggerated mechanical stress to the parts. Large boards with heavy substrates absorb these stresses better, while these methods used on ever-shrinking and complex boards can result in breakage. This brings lower throughput, along with the added costs of tooling and waste removal associated with mechanical methods.

Increasingly, flexible circuits are found in the PCB industry, and they also present challenges to the old methods. Delicate systems reside on these boards and non-laser methods struggle to cut them without damaging the sensitive circuitry. A non-contact depaneling method is required and lasers provide a highly precise way of singulation without any risk of harming them, regardless of substrate.

Flexible printed circuit ( FPC ) application technology

UV laser cutting machine processing advantages
1. The edges are neat and clean, no burrs
2. High precision, especially suitable for small radius shape cutting
3. The thermal shock to the board is small, no delamination
4. Cutting different thickness or different materials can be completed in one step
5. Bare board and PCB with installed components can be cut
6. No contact processing, so the material is not deformed
7. Automatic target recognition system ensures high edge accuracy and accurate position
8. Reduce mold making and replacement time and shorten circuit board development cycle
9. Save mold costs

Shortcomings/defects in traditional Mold/die punching

(Traditional process method- Using a die or steel die to punch out the outer shape of the piece )
1. Long cycle-time
2. Low precision, generally MAX. up to +/-0.05mm
3. Rough edges
4. Easy to strain the line due to shear stress
5. The mold needs to be remanufactured after wearing
6. There are security risks
