Process Photonics has developed the rugged FP platform, a unique workstation design that has been configured for use with industry-proven CO2 and UV laser sources.  Three basic configurations are available:

The , with an RF-excited CO2 laser for optimized machining in all common polymer materials, as well as green ceramic tape.

The , with an RF-excited CO2 laser for optimized machining in all common polymer materials, plus a UV laser for copper machining

Lasers have been used to process flex circuits for over 15 years.  The current requirements for precision processing of parts for the hard disk drive industry (suspension flex) and the electronics packaging industry (chip on flex, multi-chip modules, PCMCIA cards) are typical of the applications where lasers provide manufacturers with significant advantages. 

The FP Series form the ultimate processing workstations for flex, with high performance galvos for rapid point-to-point drilling and routing complex features.  The CO2 laser is appropriate for high speed machining (drilling, cutting and skiving) of polyimide, while the UV laser is able to machine copper and provide higher cut quality in polyimide.  In addition, the system can process glass- and aramid-reinforced epoxies and resin-coated foil for rigid and rigid-flex applications.

PPI Products

All standard systems, and most custom systems, are designed around a tubular steel weldment for support of the optical beam delivery, motion stages, power distribution, and possibly even the laser depending on the particular system. Optical components are procured from suppliers with a proven track record in quality optics and robust, damage-resistant coatings.



As a result, PPI has the capability to provide detailed support and upgrades for these products, whether related to the beam delivery, software, or process itself. PPI personnel were key to the development of the GSI Lumonics DrillStar® GS-600 and GS-800 products, as well as earlier GS systems. Let us help you maximize machine performance for your particular situation. Process development, consulting and apps lab work.



Each of the four probes as well as the galvanometer-located laser beam have access to the whole 50x50mm field, ensuring that any component location, size, orientation and component density can be accommodated. Circuit designers are no longer limited by the practical size limit on probe card designs; circuits can be as large as the panel itself.


Wafer Processing

The beam from a TEA-CO2 laser (e.g. GSI Lumonics Impact™ series) is converted through the optical beam delivery system to the desired size, shape and energy density for the process requirements. Controlling the rate of movement of the wafer under the beam, and the pulse repetition rate of the laser, defines the total dose of light seen by any particular portion of the wafer.



Laser drilling of microvias is now commonplace in the electronics packaging industry, allowing high density circuits to be made for a range of products from cellular phones and other hand-held devices to chip on flex, multi-chip modules, and PCMCIA cards. Process Photonics has developed the rugged ProVia platform, a unique workstation design that has been configured for use with industry-proven CO2 and UV laser sources.
