Ichia Swings to Profit in Q2 2018
July 17, 2018 | DigitimesEstimated reading time: Less than a minute
Taiwan-based Ichia Technologies, which manufactures flexible PCBs as well as mechanical integrated components, has reported pre-tax profits of NT$97 million ($3.2 billion) for the second quarter of 2018 following five straight quarters of losses, according to Digitimes. However, the company generated pre-tax losses of NT$26 million in the first half of 2018.
Ichia saw its June revenues fall 10% sequentially to NT$573 million due mainly to a temporary shutdown of part of its production lines in Suzhou, China, where the Suzhou Environmental Protection Bureau has launched a probe into Ichia’s local plant following accusations that it discharged polluted wastewater, and ordered it improve its wastewater processing as soon as possible. The probe, which took place between May 23 and June 27, has prompted Ichia to suspend part of its etching and copper plating production lines.
Digitimes quoted Ichia CEO Larry Sun as saying that the incident, which already affected Ichia's June revenues, will continue to impact the company's revenues in July. The Suzhou plant is expected to return to full capacity later in July.

Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
The Chemical Connection: Through-glass Vias in Glass Substrates
06/24/2025 | Don Ball -- Column: The Chemical ConnectionThis month’s theme is vias and how best to ensure via quality and reliability. I don’t have much expertise in this process area or much to contribute that most of you don’t already know. However, I’ve recently become peripherally involved in a via technology that may be of more than academic interest to some of us. It entails putting vias in a material not usually associated with PCB manufacturing: through-glass vias (TGVs) in glass substrates.

The Chemical Connection: Common Misconceptions in Wet Processing
04/28/2025 | Don Ball -- Column: The Chemical ConnectionInitially, I thought an April Fool’s column would be fun this month. I could highlight some of the crazier ideas and misconceptions I’ve witnessed over the years from potential customers and we could all have a good laugh. For example, there was a first-time buyer of a ferric chloride etcher (with no regeneration system) who was astonished to learn that he had to put fresh etchant in the system occasionally to maintain production.
