Photoresist, also known as photo-resistive material, refers to an etch-resistant thin-film material whose solubility changes upon exposure to ultraviolet light, electron beams, ion beams, X-rays, or other forms of radiation.

Overview and Basic Concepts of Flex PCB Prototypes In modern electronics design and manufacturing, flex PCB prototypes (flexible printed circuit board prototypes) have become an essential component of innovative product

PCB jumper refers to spaces reserved on a printed circuit board for connecting circuits, achieved by adding conductive wires and connectors. They serve a broad purpose in circuit design, effectively

The surface treatment process of PCB circuit boards is crucial to their performance and environmental credentials. Among these, the tin-plating process is widely favoured for its cost-effectiveness and solderability. Tin-plating

What are leaded and leadfree processes? Leaded solder typically consists primarily of tin-lead (Sn-Pb) alloys, such as the classic Sn63/Pb37 (63% tin, 37% lead), which has a low melting point

The encapsulation process, also known as the packaging process, involves the secure enclosure of semiconductor chips using specific materials. This provides effective defence against environmental degradation, ensuring stable chip operation.

Definition and Function of a PCB Board Transformer In modern electronics manufacturing, the term “PCB board transformer” is a common yet often misunderstood concept. It typically refers to a transformer

As electronic products demand increasingly diverse functionalities, pcb board structures have grown ever more complex. Constrained by spatial limitations, PCB circuit boards have progressively “evolved” from single-layer to double-layer and

Ionic cleanliness testing serves as a critical quality control measure for evaluating ionic contaminant levels on pcb boards surfaces. Its primary objective is to prevent electrical faults such as short

FR1 pcb is constructed from glass fiber-reinforced epoxy resin laminates. FR1 PCBs are rigid, flat materials composed of thin copper layers on a non-conductive phenolic resin substrate. FR1, fully known

In electronic manufacturing, circuit boards must be divided into distinct sections to meet the design requirements of various electronic products. Traditional mechanical cutting and punching techniques struggle to satisfy modern

OSP (Organic Solderability Preservative) is a surface treatment process for PCBs (Printed Circuit Boards). It involves coating the copper foil surface with an extremely thin organic protective film (approximately 0.2-0.5μm

What does FPC stand for? FPC stands for Flexible Printed Circuit, known in Chinese as a flexible printed circuit board, commonly abbreviated as a flexible board. FPC is a highly
