01 – ODM ODM (Original Design Manufacturer) refers to a manufacturer that not only produces products but also designs them. Originally, OEMs focused solely on production while design was managed by brand companies. However, as manufacturing alone often yielded low profits, manufacturers began expanding upstream by developing in-house design capabilities. Some Independent Design Houses (IDHs) also […]
Differences and characteristics of analog and digital signals In electronics, signals can be divided into two types: analog signals and digital signals. They have obvious differences and characteristics in terms of transmission methods, processing methods, accuracy, noise, etc. The following will introduce the differences and characteristics of analog and digital signals from these aspects in

1.Diverse Pricing Due to Different PCB Materials Taking a standard double-sided PCB as an example, the materials used can vary. The base material is typically FR4, with thicknesses ranging from 0.2mm to 3.0mm, and copper thickness ranging from 0.5OZ to 3OZ. These variations in material alone create significant price differences. In terms of solder mask

01 What is PCB surface treatment process? Copper surfaces on PCB without solder mask coverage, such as solder pads, gold fingers, mechanical holes, etc. If there is no protective coating, the copper surface is easily oxidized, which affects the soldering between bare copper and components in the solderable area of the PCB. As shown in the
A rigid-flex PCB is a new type of printed circuit board that combines the durability of rigid PCB and the flexibility of flexible PCB (FPC). Among all types of circuit boards, rigid-flex PCB offer the strongest resistance to harsh environments, making them popular among manufacturers of industrial control, medical, and military equipment. WonderfulPCB is also gradually increasing the
SMT (Surface Mount Technology) processing is a crucial technique in the manufacturing of electronic devices. For procurement personnel new to this field, understanding the process flow of SMT assembly is fundamental. This article outlines the main steps in SMT processing to help you quickly grasp the core aspects of this technology. Basic Concept of SMT
1. FPC Material Cutting Except for certain materials, most of the materials used in flexible printed circuits (FPC) come in rolls. Since not all processes require roll-based techniques, some processes, such as drilling metallized holes in double-sided flexible PCB, must be done with sheet-form materials. The first step for double-sided flexible PCB is cutting the material
PCB (Printed Circuit Board) is an important electronic component that serves as a support structure for electronic components and a carrier for electrical connections. It is called a “printed” circuit board because it is produced using electronic printing techniques. PCB are one of the essential components in the electronics industry. Almost every electronic device, from small items
What is the PCB Fabrication Process? As the carrier of electronic components, PCB plays a vital role in the electronics manufacturing industry. Its production process is complex and precise, directly affecting the performance and quality of the final product. WonderfulPCB, a trusted SMT processing factory, provides a detailed analysis of the PCB production process to
PCBA Assembly Methods: SMT and DIP PCBA (Printed Circuit Board Assembly) processing involves a complete set of steps including PCB manufacturing, SMT (Surface Mount Technology) processing, DIP (Dual In-line Package) insertion, quality inspection, testing, and assembly to form a finished electronic product. This process is referred to as PCBA processing, and the resulting circuit board
