PCB Fabrication
Here, you can acquire professional knowledge covering the entire chain from PCB design to assembly, as well as precise analysis of the latest trends in the electronics industry.
Industrial PCB Production: Process & QA
Industrial PCB production turns an approved circuit-board design into bare boards and, when ordered, populated assemblies for industrial equipment. The route includes fabrication, component assembly, inspection and agreed testing. Approval depends on the specified build, operating conditions and acceptance criteria. A motor controller, sensor interface and cabinet-mounted control board can require different materials, mechanical support…

HDI PCB: Stackup, Microvias and Design
An HDI PCB, or high-density interconnect printed circuit board, uses fine conductors and compact interlayer connections to fit more wiring into a given area. Laser-drilled microvias and thin buildup layers help connect dense component pads without using a full-thickness hole at every connection. The design question is whether those features solve a routing constraint worth…

Rigid PCB: Materials, Construction and Design Choices
A rigid PCB, or rigid printed circuit board, supports components and connects them through copper conductors on a substrate designed to retain its shape in service. It suits electronics whose circuitry stays fixed within an enclosure, rather than bending during use. Choosing one means matching its construction to the circuit, mounting, connectors and environment. Layer…

Flex PCB: Types, Materials, Stackup and Design Rules
A flex PCB is a circuit built on a flexible polymer film, usually polyimide, with copper conductors bonded to it and a coverlay protecting them. That is the definition, and it is the part already answered above the search results. It is not the part that decides whether your build works. Four questions decide that,…

Flex PCB Bend Radius: How to Calculate and Specify It
You have a stackup, a housing envelope, and a mechanical engineer asking for a flex PCB bend radius. The answer is not a lookup table; it is a strain calculation, and the multipliers in the tables are what that calculation returns once you fix a stackup. Every published multiplier, whether it reads 6×, 10×, 12×,…

Reflow Soldering Guide: Process, Profile and Defects
Reflow soldering is the process that attaches surface-mount components to a printed circuit board by heating stencilled solder paste until it melts, wets the component terminations and forms the joint on cooling. It is the primary assembly method for almost every modern electronic product, and it is the step where the most expensive mistakes become…

Copper Clad Laminate (CCL): Types, Manufacturing, Performance, and Standards
Copper clad laminate, or CCL, is a base material from which PCB conductors are formed. It consists of copper foil bonded to an insulating material such as cured glass-reinforced epoxy, a flexible polymer film, or a thermally conductive dielectric on a metal base. In a conventional multilayer rigid PCB, patterned CCL commonly becomes a core.…

JLCPCB vs PCBWay: Which PCB Manufacturer Fits Your Project? (2026)
For a straightforward PCB prototype or a small assembly order that fits JLCPCB’s Economic PCBA rules, start with JLCPCB, especially when the components are already in its inventory. For rigid-flex or extensive custom fabrication requirements, shortlist PCBWay early. These recommendations follow from JLCPCB’s economical assembly tier and PCBWay’s documented advanced manufacturing options. The JLCPCB vs…

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.…

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…
