Product Life Cycle (PLC) is a framework used to manage a product throughout its entire journey—from the initial idea and market validation to development, production, continuous improvement, and eventually End of Life (EOL). While the exact process may vary from company to company, most follow a similar path to guide products from concept to market in a structured and controlled way.

In the electronics industry, PLC is more than just tracking whether a product grows or declines in sales. It helps companies make decisions, align cross-functional teams, manage risk, and balance time, cost, quality, and market expectations throughout development and production.

What is DFX? Understanding Common DFX Design Methods Like DFM and DFA

DFX is the general term for “Design for X.” It means considering all aspects of a product’s entire lifecycle right from the beginning of the design stage.

DFX originally stood for “Design for Excellence.” The word “Excellence” can be extended to many different areas, with the goal of making the product as outstanding and perfect as possible. Since perfection is almost endless, people started replacing “Excellence” with specific goals such as Manufacturability, Testability, Inspection, Repairability, Recycle, Cost, and so on — each representing an important aspect of the product’s lifecycle.

Managing Color Variation in Plastic Parts: 7 Practical Tips for Better Color Control

Pantone color guides

A few days ago, a reader asked Workingbear about color variation issues between plastic injection-molded parts, and whether there are any good ways to better control color consistency.

The problem was probably caused by the purchasing team trying to reduce supply chain risk by placing different plastic molds with different injection molding vendors. During incoming inspection, each individual plastic part passed the color specification requirements and stayed within the defined upper and lower tolerance limits. However, once all the plastic parts were assembled into the final product, obvious color mismatch issues became visible between the parts.

MRB Decision-Making and Cosmetic Quality Evaluation for Plastic Parts

製造工廠的MRB會議及塑膠件品質判斷

When Workingbear first joined an electronics final assembly factory as a product/process engineer, I often had to attend MRB (Material Review Board) meetings. From time to time, people would come to me asking me to evaluate rejected parts and decide whether they could be waived for use. Otherwise, the production line could face material shortages or even a shutdown.

What I disliked the most back then was dealing with rejected plastic parts. It was always a tough call. Unfortunately, in final assembly, more than 70% of rejected materials were related to plastic components… not exactly a fun situation.

Why Electronics Assembly Factories Need IQC: Three Key Purposes Explained

Why Electronics Assembly Factories Need IQC: Three Key Purposes Explained

In most electronics assembly organizations, there is a function called IQC (Incoming Quality Control). The primary purpose of IQC is to screen incoming materials to ensure they meet drawing specifications, preventing defective parts from directly entering the production line. This helps avoid defective output and even potential line shutdowns.
