Scrap and NG in Magnetic Shielding Product Manufacturing in Thailand

Magnetic shielding products made from high-permeability alloys like Mu-metal, Permalloy, or similar nickel-iron materials play a critical role in protecting sensitive electronics from electromagnetic interference (EMI) and radio frequency interference (RFI). These shields appear in medical equipment, aerospace components, automotive sensors, audio devices, and industrial electronics. In Thailand’s growing manufacturing sector — with many facilities […]

Understanding Scrap and NG in Automotive Manufacturing

In automotive spare parts manufacturing—whether producing engine components, wiring harnesses, plastic parts, or machined parts—scrap and NG are critical indicators of process health. ⚙️ Major Processes Where Scrap and NG Occur 🟠 1. Incoming Material Inspection (IQC) Common Issues: Impact:Poor incoming quality leads to defect multiplication across the production line. 🔴 2. Machining Processes (CNC, […]

Bare PCB Manufacturing – High Scrap Areas

Scrap and NG (non-good) are usually not random—they concentrate in a few high-risk processes where variation, material sensitivity, and process control gaps exist 🔷 1. Bare PCB Manufacturing – High Scrap Areas 🟠 a) Lamination Process Common NG: Why it happens: 👉 Impact: Internal defects → cannot rework → 100% scrap 🟠 b) Drilling Process […]

BOI Scrap Management Risks That Many Companies Overlook

Companies operating under the privileges of the Thailand Board of Investment (BOI) must carefully manage production scrap and waste materials. Improper scrap handling can lead to compliance issues, tax reassessment, or even suspension of BOI privileges. Many factories unintentionally create risks due to weak documentation, poor traceability, or misunderstanding BOI requirements. 1. No Independent Verification […]

Major Areas of NG & Scrap in Cable and Wire Manufacturing

Cable factories see most defects coming from conductor processing, insulation, extrusion, and final testing. 1. Conductor Preparation (Wire Drawing & Stranding) This is the foundation stage, and defects here carry forward. Common NGs: Root causes: 👉 Impact: Electrical resistance issues, mechanical weakness, rejection in later stages 2. Insulation Extrusion (Highest Scrap Contributor) This is usually […]

Major Scrap / NG Sources in PCB (PCBA/SMT) Factories

Scrap and NG (Non-Good) in a PCB/PCBA factory don’t come from one single issue—they’re usually a combination of design gaps, process variation, material defects, and handling problems. 1. Soldering Defects (Top Contributor) This is usually the #1 scrap driver in SMT lines. Common issues: Root causes: 2. Component Placement Defects Errors during pick-and-place process. Typical […]
