10 µF on the BOM: Check Effective Capacitance Before Approving the Build

October 21, 2026

10 µF on the BOM: Check Effective Capacitance Before Approving the Build 中文摘要本期为常青工程内容，非当天新闻：BOM 上的 10 µF，并不直接等于上电后的有效电容量。围绕 X5R/X7R 类 MLCC 的直流偏压效应，说明如何保留准确料号、在一致条件下比较资料、审批替代料，并区分元件测量与整机验收。不给出通用降容比例，不把概念曲线当实测，也不宣称 PCBDOG 具备未经确认的专项测试能力。配图另在 dot 对话中以原生附件交付；本邮件是完整文字版，不含图片附件。原创技术概念图保留原始 logo 及完整页脚。曲线为定性示意，不是实测数据，也不是任何具体料号的规格。 Evergreen engineering content, not today’s news.

Kelvin Sensing: Preserve the Measurement Path

October 20, 2026

Kelvin Sensing: Preserve the Measurement Path A current-sense resistor may occupy only a small corner of a robot controller or industrial drive. Yet the voltage measured across it can influence protection, current regulation and system diagnostics. Specifying its resistance in the BOM is only the beginning. The PCB pickup points, component terminals and manufacturing handoff must preserve the intended measurement path. Consider an illustrative DC example, not a PCBDOG test result. A 20 A curren
A finished PCBA need

October 14, 2026

A finished PCBA needs a defined software identity as well as a hardware identity. For a robot controller, industrial sensor or edge-AI device, an untracked firmware change can make two apparently identical assemblies behave differently. The practical question before production is simple: can the team identify the approved image, the compatible board revision and the evidence required to release each unit? What the programming tools actually establish Official documentation separates several ope
Before the First Build: Make Edge-AI Hardware Testable

October 10, 2026

Before the First Build: Make Edge-AI Hardware Testable A working prototype still needs a repeatable build process An edge-AI board may run a convincing demonstration on an engineer’s desk. Moving that design into a repeatable PCBA build introduces another set of questions: How will each board be powered safely, programmed consistently, checked against defined limits, and ed to its results? These questions matter to robotics, industrial sensing, connected instruments, and intelligent gateways. A

PCB Cost Is Not Decided by the Quotation — It Is Decided Much Earlier

May 20, 2026

In PCB and PCBA manufacturing, many people believe the cost is decided when they receive a quotation. But in reality, the cost is often decided much earlier: During design. During material selection. During stack-up definition. During DFM review. During component sourcing. During the customer’s decision-making timeline. Today, PCB manufacturing is facing a more complex environment than before. Raw material prices are changing faster. Glass cloth, copper foil, resin systems, and high-speed lamin

Don't Let Mediocre DFM Kill Your Product: Why Connector

March 19, 2026

Dont Let Mediocre DFM Kill Your Product: Why Connector Standoff Design is Non-Negotiable In the PCBA industry, the true caliber of an SMT provider is revealed by their stance on Connector Standoff design. Many factories issue EQs suggesting: Please remove the standoff and use a flush-mount design to avoid soldering defects and AOI false alarms. At PCBDOG, we believe: If your supplier suggests flying low, they are likely trading your products long-term reliability for their own process convenien
