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.”

Preventing De-wetting Defects In Immersion Tin Soldering

01/04/2023 | Britta Schafsteller, Atotech
Immersion tin is well accepted as a high-reliability final finish in the industry. Due to its excellent corrosion resistance, it exhibits major market shares, particularly in the automotive industry. During the soldering process, an intermetallic compound (IMC) is formed between copper and tin. One remaining concern in the industry is the potential impact of the IMC on the solderability of the final finish. In this article, typical failure modes in soldering immersion tin are described and correlated to potential root causes for the defects.
