6 Methods for Troubleshooting PCB Short Circuits

2026-05-06

Common types of circuit board short circuits are classified as follows by function: soldering shorts (e.g., solder bridging), PCB internal shorts (e.g., residual copper, misaligned vias), component shorts, assembly shorts, ESD/EOS breakdown, inner-layer micro-shorts in circuit boards, electrochemical shorts (e.g., chemical residues, electromigration), and shorts caused by other reasons.

My PCB Prototype Arrived—My Mentor Sighed in Silence After Checking It

2026-05-06

Many electronics engineers have made mistakes with component footprints during PCB layout. The footprint is either oversized or undersized, and in some cases, component interference occurs. As a result, components cannot be soldered onto the fabricated PCB, forcing manual jumper wire fixes. In severe cases, the entire board is scrapped. For example, the footprint of U8 in the figure below is designed too small, making chip soldering impossible.

What is BGA Reflow Warpage? How to Solve BGA Warpage During Reflow Soldering?

2026-05-06

An electronic product manufacturing factory produces a high-performance computer motherboard with a large number of BGA-packaged devices. During the manufacturing process, the factory found that some motherboards suffered from BGA warpage during reflow soldering, resulting in poor soldering, degraded product performance, and severely impaired product reliability and quality. After investigation and analysis, the specific causes of the warpage were identified. Let’s take a closer look.
