ESI Launches New Laser Drilling System for HDI Rigid PCB Manufacturing


Reading time ( words)

Electro Scientific Industries Inc. has launched its Geode laser-based micro-via drilling system for high-density interconnects (HDI) on rigid printed circuit boards (PCB). This new entry combines a CO2 laser and advanced beam control capabilities to deliver improved throughput and accuracy from a system that is significantly smaller and lighter than current competitive offerings. The system's sophisticated beam steering and pulse shaping technologies provide the flexibility and control that will be required for 5G applications using high-frequency compatible materials and finer-pitched interconnects fabricated with modified semi-additive processes (mSAP).

"The Geode leverages ESI’s decades of experience in laser optics and laser-material interaction to deliver a system that out performs and out produces anything on the market," stated John Williams, vice president of marketing, ESI. "Other HDI laser systems are based on legacy mechanical drilling platforms that were large and heavy, the Geode system’s design is based on a lighter-weight, smaller-footprint platform that is purpose-built from the ground up specifically for HDI laser processing. This design not only helps Geode meet the high-accuracy, high-throughput requirements of processing applications such as 5G, but also makes it a more cost-effective platform for our customers to install and maintain."

The Geode system uses a powerful 9.4µm pulsed CO2 laser, emitting infrared radiation ideally-suited for rigid PCB materials. Its HyperSonix technology shapes laser pulses to improve throughput and via quality. AcceleDrill distributes pulse energy to improve throughput and via metrics and also permits multiple via sizes in a single pass. VDC (via density compensation) controls local heating to minimize heat-affected zones and improve accuracy, throughput and diameter stability. The Geode system is the first CO2 laser via drilling system to incorporate such high level beam control and beam steering technologies. 

ESI is currently exhibiting at the HKPCA & IPC Show 2018, being held this week in Shenzhen, China. EIS is at Booth 1Q01.

ICT technical director Bill Wilkie is well-known for choosing notable venues for Institute of Circuit Technology events, and his choice for this year’s Annual Symposium was the National Motor Museum, located in the village of Beaulieu in the heart of the New Forest, a national park in the county of Hampshire in Southern England. The region is known for its heathland, forest trails and native ponies.

Show & Tell: Corporate Awards Bestowed by IPC

04/03/2018 | Patty Goldman, I-Connect007
Every year IPC recognizes two companies that have made significant contributions to IPC and the electronics industry. These awards are named after industry executives who were themselves significant and outstanding contributors: one for a PCB fabricator company and one for an electronics manufacturing services (EMS) company. This year’s recipients were Northrop Grumman and Rockwell Collins, respectively.
