What Is an Open Circuit? (Definition & Principles) An open circuit is an electrical circuit in which the current path is broken, preventing electricity from flowing. Even if a voltage source is connected, no current will flow unless the circuit is closed, meaning all connections are complete and continuous. Open Circuit Definition (Simple Terms) An […]

The electronics we carry every day—from smartwatches to EV-power modules—are possible largely because of one manufacturing leap: the surface-mount device (SMD). By allowing parts to be placed directly on the surface of a printed-circuit board (PCB), SMD technology condensed entire radios, computers, and sensors into pocket-sized form factors. Introduction 1. The Evolution of Electronic Assembly […]

Introduction In today's fast-paced world of electronics manufacturing, the need for smaller, more efficient, and reliable devices has never been greater. The key to achieving these goals lies in two fundamental technologies that have revolutionized how modern electronics are built: SMD (Surface-Mounted Devices) and SMT (Surface-Mount Technology). Both SMD and SMT have become essential in the design and […]

Introduction Surface Mount Technology (SMT) has revolutionized electronics manufacturing by enabling ever-smaller, higher-performance circuit boards. From the smartphones in our pockets to advanced automotive control units, SMT underpins the devices we rely on every day. In this article, we'll demystify SMT—what it is, how it works, and why it matters—so that engineers, hobbyists, and decision-makers […]

Printed Circuit Board Assembly (PCBA) plays a pivotal role in the world of electronics manufacturing. Think of PCBA as the essential step that brings a PCB to life, making it ready for use in everything from consumer gadgets to complex medical equipment. In this article, we'll break down PCBA—its definition, types, processes, and quality control—giving […]

Selecting the right PCB (Printed Circuit Board) material is critical for ensuring the performance, reliability, and longevity of electronic devices. Different types of circuit board substrates—such as FR-4, aluminum, flexible, paper-based, and fiberglass—are designed for specific applications. High-performance materials like ceramic and polyimide substrates are also available for specialized use cases.

At Fast Turn PCB, we specialize in delivering cutting-edge surface treatment solutions that enhance the reliability and performance of your printed circuit boards (PCBs). One of our core competencies is Gold Finger plating, powered by the Electroless Nickel Immersion Gold (ENIG) process. This technology is essential for PCBs used in telecommunications, automotive electronics, medical equipment, and industrial control systems.

In the field of electronic manufacturing, rapid innovation and diversified product demands require highly flexible and precise production solutions. At Fast Turn PCB, we specialize in small to medium batch and multi-variety PCB and SMT assembly services, offering strong technical capabilities in high-layer count boards, HDI (High-Density Interconnect), and rigid-flex PCBs.

Fast Turn PCB provides turnkey value-added services that go beyond basic PCB production to help customers accelerate time-to-market and streamline their supply chain. Our comprehensive solutions include custom mold making, plastic injection molding, and cable assembly, along with essential services such as IC programming, ICT, FCT, and aging tests—all integrated under one roof to ensure speed, consistency, and quality.

Flying Probe Testing (FPT) is a type of ICT that uses moving probes instead of a fixed test fixture. It's widely used for prototypes, new product introduction (NPI), and low-volume PCB assembly, offering fast setup and high test coverage without the need for a custom test jig.

In SMT (Surface Mount Technology) processing, inspection is critical to ensuring high product quality and production efficiency. Various testing and inspection methods are used throughout the assembly process to detect defects early and maintain reliability. Below are the most common testing methods applied in SMT PCB assembly:

In electronics manufacturing, PCBA programming (commonly known as burning or downloading) refers to the process of writing pre-compiled code into the memory of a PCBA board. A reliable and precise programming process ensures the product operates as designed and delivers stable performance. This guide provides a comprehensive overview of the PCBA programming workflow, common methods, verification, testing, error handling, and the value-added services we offer to support high-quality production.
