Candor Improves Positive Acting Liquid Photoresist Process; Installs ENIPIG Line

Reading time ( words)

Toronto-based high technology circuit board manufacturer Candor Industries has recently taken steps to improve certain aspects of their fabrication processes. 

The team has improved their rigid-flex manufacturing process utilizing positive acting liquid photoresist allowing them to do via filling on rigid areas. By improving their laminating processes and approaching rigid flex in a novel way they have successfully eliminated several processing steps in the manufacture 4-6 layer rigid flex. The elimination of these steps aligns with their simplified process criteria allowing the following to be available for their customers:

  • 4-6 layer rigid flex can be done in 5 days
  • Even dielectric across rigid areas
  • Via filling capabilities for rigid-flex boards

In addition to the photoresist improvements Candor has also recently installed an ENIPIG (Electroless Nickel Immersion Palladium Immersion Gold) line. With the ever rising price of gold, Candor sought out a more affordable alternative to electrolytic nickel gold and electroless nickel electroless gold for their customers that resulted in the ENIPIG installation. Rather than putting 50 micro inches of gold, we put 2-4 micro inches of palladium, saving the customer money. In addition to the price, it also provides the combined benefits of exceptional shelf life, gold wire bondability, solder joint reliability and usage as a press contact surface.

Sunny Patel, Candor’s Technical Sales Manager states, “We’re always seeking new ways to improve our services for our customers.   With these changes we’ve made a two pronged improvement by finding ways to lower costs and provide superior, faster products.”

How to Feed Test Data Back to Engineering for Process Improvement

08/01/2019 | Todd Kolmodin, Gardien Services
Some people think of the PCB manufacturing process as a black box: design data goes to the manufacturer (fabrication house), and magically, the finished PCB is produced. While it may have been like that in the past, in actuality, fabricating PCBs today is quite a ballet of processes.

A Guide to High-reliability PCBs from Design to Specification

07/24/2019 | Jeff Beauchamp, NCAB Group
Creating reliable PCBs is an outcome of considering all aspects that can affect reliability as early as possible in the design process. The further down the design process, the more expensive and risky it can be to fix. As they say, everything starts with the design. Because a good board design improves the reliability of the end product and lessens the risk of failure.
