What is semiconductor packaging? Semiconductor Packaging is the process of processing a tested wafer into an individual chip according to the product model and functional requirements. The purpose of traditional packaging is to fix, lead and seal the cut chip, but with the advent of the post-Moore’s Law era, more and more steps that need
HDI PCB definition, High Density Interconnect Board, is a circuit board with high line distribution density using micro-blind/buried hole technology. It is able to achieve higher line density and finer wiring in limited space to meet the demand for miniaturisation, high performance and high reliability of modern electronic products. In the field of pcb board,
On a circuit board, RT usually stands for Thermistor, a component that is extremely sensitive to temperature. The resistance value of a thermistor changes significantly with temperature, so by measuring its resistance value, we can accurately deduce the current ambient temperature. This characteristic makes thermistors play a vital role in circuit functions such as temperature
PCB test points may look like just some pads or exposed copper skins, but their role in the entire production, debugging, testing and repair process is very critical. If the test points are not reasonably arranged, it will lead to difficult to test the circuit board, debugging time becomes longer, the difficulty of rework increases,
A transparent flexible PCB is a pcb board that can be bent and has a certain degree of flexibility without affecting its functionality. It is made of flexible materials such as polyimide or polyester film, allowing for compact circuit connections in a given space. Transparent flex pcb is lightweight and durable. It is this property
FPC flexible circuit board is widely used in modern electronic products due to their thin, lightweight and bendable characteristics. However, its unique physical properties also bring many challenges to the welding process, requiring fine process control and specialised coping strategies. Flexible circuit boards in the welding process should pay attention to: Quality inspection is a
In the production of flex board, material deformation and delamination are important factors affecting product quality. In order to avoid such problems, the following detailed coping strategies can be adopted: Substrate selectionThe choice of material directly determines the basic bending performance of flex board. In terms of substrates, polyimide (PI) and polyester (PET) are commonly
High speed digital pcb is circuit boards that can support high speed digital signal transmission, and are usually used in scenarios where the frequency of digital logic circuits reaches or exceeds 45MHz-50MHz, or where the delay of digital signals in circuits on the transmission line is greater than 1/2 rise time. Compared to traditional analogue
Leadless chip carrier refers to a chip substrate material that does not contain lead. Traditional chip carriers often use leaded materials because leaded materials have high plasticity and are easy to process during manufacturing, but leaded chips are harmful to the environment and the human body. Leadless chip carrier is widely used in the manufacture
PCB board assembly processing, there may be a variety of defects, these defects can be categorised as the following major aspects, designed to improve product quality and reduce the defective rate. Welding defectsWelding is a key part of PCB board assembly processing, common welding defects include: False soldering (Dry Joints/Cold Solder): refers to incomplete solder
