Youtube: 5 Key Mindsets Before You Start Writing an 8D Report

post on November 26, 2025

Do you ever find yourself being less than honest when writing an 8D report to a customer? Or maybe in your company, the 8D report is more like a “one-man show”? What should we really pay attention to when writing an 8D report?

Here, Workingbear wants to share some personal thoughts about the 8D report. To be clear, Workingbear isn’t exactly a quality management expert — just someone who has spent years in the field, taken some basic quality-related training, written a few 8D reports, and reviewed plenty from suppliers. These experiences brought some insights worth sharing. Of course, if you have different opinions or questions, feel free to bring them up for discussion.

Lessons from My First Days on the Electronics Assembly Line: How I Earned Respect as a Rookie Engineer

post on November 20, 2025

Thinking back to my first day working at an electronics assembly factory, I was hired as a Product Engineer. This role is actually quite similar to that of a Process Engineer, but at that time, Workingbear only had experience in IC packaging or Semiconductor assembly and test (OSAT) company — so when it came to assembly line operations, I was totally clueless.

PCB Edge Removal and De-paneling: Stamp Hole Design

PCB Edge Removal and De-paneling: Stamp Hole Design

In most PCB (Printed Circuit Board) designs, panels are usually connected using V-cuts or tabs/ribs, and then separated with a V-cut scoring machine or a router de-panel machine. However, besides these two common connection methods, there’s another approach called the stamp hole design. Workingbear personally isn’t a big fan of this method, which is why it hasn’t been covered until now.

The name “stamp hole” comes from its resemblance to a sheet of postage stamps — small holes are drilled along the break line, allowing the boards to be snapped apart by hand or with pliers. This design makes manual de-paneling easy and doesn’t require special equipment, unlike the other two methods that need a scoring or routing machine.

Attitude Determines Everything — The Making of an Engineer

Attitude Determines Everything — The Making of an Engineer

An engineer must be grounded, hands-on, and unafraid to get their hands dirty — learning by doing and using practical experience to verify theory.

Because of his job, Workingbear often visits various professional electronics manufacturing service (EMS) factories and spends a lot of time on production floors. He frequently interacts with process engineers and test engineers. To these engineers, Workingbear always emphasizes two things:

1. Do it yourself.
2. Always ask “why.”

PCB Edge Removal and De-paneling: Precautions for Manual Breaking

PCB Edge Removal and De-paneling: Precautions for Manual Breaking

There are many ways to de-panel or remove the edge rails of a PCB, but the simplest and cheapest method is manual V-cut breaking. However, this method can easily lead to uncontrolled quality issues. Before using manual breaking, it’s important to confirm that the board really cannot be processed with a V-cut scoring machine, or that the components on the PCBA are strong enough to handle bending stress without damage.
