What Is a Through Hole? PCB Types, Uses, and Design Guide
A through hole is an opening that passes completely from one side of a printed circuit board (PCB) to the other. It may be plated with conductive copper to create an electrical connection, or left unplated for mechanical use. Through holes are commonly used for component leads, connectors, vias, mounting hardware, alignment pins, and slots.…
PCB Material Guide: Types, Properties, and Selection
PCB material affects far more than the physical strength of a circuit board. It influences impedance, signal loss, heat dissipation, dimensional stability, assembly reliability, manufacturability, lead time, and cost. A material that works well for a basic controller may fail in a 77 GHz radar module, a high-current LED board, or a rigid-flex medical device.…
Flex PCB: Types, Design, Manufacturing & Uses
Modern electronic hardware design operates under punishing spatial constraints. Across consumer wearables, portable diagnostic tools, electric vehicle (EV) battery arrays, and avionics, the engineering challenge is uniform: pack dense computing power, sensor suites, and high-speed data paths into non-rectangular, ergonomically sculpted, or continuously moving mechanical envelopes. Standard rigid printed circuit boards (FR-4) cannot bridge these…
Multilayer PCB: Design, Stackup & Applications
A multilayer printed circuit board (PCB) integrates three or more conductive copper layers separated by insulating dielectric materials to handle dense routing, high-speed signals, and rigorous electromagnetic compatibility (EMC) requirements. Choosing between a 2-layer, 4-layer, 6-layer, or higher stackup depends on component density, return-path continuity, controlled impedance targets, and thermal dissipation needs. Early stackup planning…
Rigid PCB: A Complete Guide to Types, Design, and Uses
A rigid PCB is a non-flexible printed circuit board constructed from solid substrate materials—most commonly fiberglass-reinforced epoxy like FR-4—designed to mechanically support and electrically connect electronic components in a fixed form factor. It remains the foundational standard for modern electronics due to its unmatched mechanical stability, high component density, broad material compatibility, and cost-effective scalability.…
Copper Clad Laminate Guide for PCB Materials and Features
What is Copper Clad Laminate (CCL)? At its core, Copper Clad Laminate (CCL) is the foundational composite material used to construct printed circuit boards (PCBs). It is created by taking a reinforcing substrate—most commonly woven fiberglass fabric or cellulose paper—impregnating it with a high-performance insulating resin, and cladding it on one or both sides with…
PCB Supplier Qualification Checklist [2026 Guide]
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…
JLCPCB vs PCBWay: Which PCB Manufacturer Is Better?
JLCPCB and PCBWay are two of the best-known Chinese PCB manufacturers for prototypes, PCB assembly, and low-volume production. Both provide online quotations, international shipping, and a wide range of manufacturing options—but they are not identical. The short answer is that JLCPCB is often the more convenient choice for inexpensive standard boards and highly automated PCB…
