Quality isn't just a slogan — it's the foundation of our business

Multi-Stage Inspection for Uncompromising Quality

At Chyun-Yih Technology, we understand how much quality matters.

It starts with a multi-layered, uncompromising inspection process. True quality assurance comes from combining the judgment of experienced professionals with the precision of advanced technology.

Before shipment, every product is inspected with CCD optical sorting machines and coordinate measuring machines (CMM), which verify flatness and dimensional tolerances respectively against our customers' strict specifications.

A final inspection by our experienced team reflects our commitment to high quality and gives our customers complete peace of mind.

FAQ

Q: What is the lead time for your products?

A: Standard products have a lead time of 4–6 weeks. Custom products are made to order and not held in stock, so production begins only after an order is placed, with a lead time of 5–8 weeks.

Q: How do you develop a product and bring it into production?

A: Once we have confirmed the customer's requirements and reached agreement on development, the process consists of three phases. Phase 1: We verify that all materials comply with relevant regulations and begin sample production. While confirming feasibility for mass production, we send samples to the customer for approval and sign-off on the product approval sheet. Phase 2: We move into mass production while fine-tuning quality control, until production is stable and the final mass-production plan is agreed upon with the customer. Phase 3: We establish a production work plan (covering materials, processing methods, inspection procedures, assembly, packaging, etc.), and all records are archived and maintained.

Q: What inspections do you perform on incoming semi-finished goods, and how do you handle nonconforming (NG) items?

A: We apply an AQL 0.65 (Acceptable Quality Level) acceptance standard unless the customer specifies otherwise, with sampling inspections for basic appearance and functionality. Areas prone to deformation or frequent cosmetic defects receive 100% inspection. When occasional nonconformities occur, we do not keep excess NG items on site. A portion is set aside for records, and the rest are returned to the supplier or subcontractor for root cause analysis and process improvement.
