PCBサプライヤー適格性確認チェックリスト［2026年版ガイド］
A PCB supplier qualification checklist helps engineers and buyers verify whether a PCB fabricator, PCBA supplier, or EMS partner can meet the product's technical, quality, delivery, and documentation requirements before production starts. ISO describes ISO 9001:2015 as a globally recognized quality management standard for improving performance and maintaining a quality management system (ISO, 2026). In…
PCB DFM Checklist
A PCB DFM checklist helps engineers and buyers catch manufacturability problems before a board is quoted, fabricated, assembled, or released to production. The goal is to confirm that the supplier can build the design with the required stackup, tolerances, finish, test plan, and documentation. DFM review reduces engineering holds and helps buyers compare suppliers. If…
PCBビアガイド：種類、設計ルール、選び方のヒント
A PCB via is a plated interconnect that lets signals, power, ground, or heat move between copper layers in a printed circuit board. Via choice affects routing density, fabrication cost, assembly yield, signal integrity, and thermal performance, so it should be part of stackup and DFM planning, not a cleanup step at the end. For…
パワーPCBと電源PCBの設計ガイド
A power PCB is the circuit board that receives, converts, regulates, distributes, or monitors electrical power. A power supply PCB is a more specific type of power PCB that converts an input source—such as AC mains, a battery, USB power, or a DC bus—into stable output voltage rails for an electronic product. The quality of…
FR4基板ガイド：FR4の材料特性、用途、設計のヒント
FR-4 is the standard base material used for most printed circuit boards. It is a rigid composite made from woven glass cloth and epoxy resin, usually supplied as copper-clad laminate so copper circuits can be formed on one or both sides. An FR-4 PCB is therefore a circuit board built on an FR-4 substrate. It…
IPC-A-610：実装受入れの完全ガイド
IPC-A-610 is the acceptance standard that decides whether a finished printed circuit board assembly is good enough to ship. It is the document your contract manufacturer's inspectors work from, the one your quality team argues about, and the one your purchase order probably cites without you ever having read it. Most engineers meet IPC-A-610 the…
SMTとは：表面実装技術をわかりやすく解説
SMT means Surface-Mount Technology: a method of attaching electronic components directly onto the surface of a printed circuit board (PCB). Rather than inserting long component leads through drilled holes, SMT uses small surface-mount components that are placed on solder-coated pads and permanently connected through controlled heating. In practical terms, SMT is what makes modern electronics…
Dual Inline Package Meaning: Pinout, Dimensions & Assembly Guide
A dual inline package (DIP) is a component package with two parallel rows of leads. Many DIPs are inserted into holes in a circuit board or a socket. The package describes the part's physical form; it does not tell you what the circuit inside does. For a board designer, identifying a DIP is only the…
PCBA File Requirements for Flawless Manufacturing
When preparing your printed circuit board design for assembly (PCBA), providing the right manufacturing files is the difference between a smooth product launch and a costly, delayed nightmare. While most Contract Manufacturers (CMs) will hand you a basic checklist asking for a BOM and Gerber files, modern Turnkey PCB Assembly requires far more comprehensive data…
