Kingford focus on the high-quality PCBA order demand of "Multiple varieties, medium and small batch, and short lead time".


Guide to Defect detection methods for flexible circuit boards

The market share of FPC is increasing with the development of miniaturized and portable electronic products. However, FPC may have defects such as open circuit, short circuit and line width discrepancy in the process of processing, feeding and mounting.

Description of three main functions of flexible circuit boards

The challenge for the flexible circuit industry is to take advantage of its technological advantages and stay abreast of computers, telecommunications, consumer demand, and dynamic markets.

PCB Introduction to printed circuit boards

In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.

Basic knowledge of PCB circuit boards

it is at least attached with a conductive graphic, and cloth holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the chassis of the previous device electronic components, and realize the mutual connection between e

Implanted chips have become a reality, ceramic circuit boards

Human body is a very sensitive organism, if disorderly implantation, the human body will reject many things, serious and even life-threatening, which is why ceramic circuit board is said.

The difference between positive and negative PCB circuit boards

Circuit board negative circuit or copper surface is transparent, positive circuit or copper surface is black

Why should there be a test site when producing PCB boards

In the mass production factory, there is no way for you to use an electric meter to slowly measure the correct Circuit of every resistor, capacitor, inductance and even IC on each board. Therefore, the so-called ICT(in-circuit-test) automatic Test machine

PCB boards often peel off the original size Reasons

A typical manufacturer can only request it twice per production cycle, and only check it once every few months. IR testing in simulated batches also prevents more spills of defective products, which are a prerequisite for quality PCB factories. In additio

Technical requirements for substrates for PCB circuit boards

In order to improve the technical performance of the printed circuit board, we must first improve the performance of the printed circuit substrate board, and ensure the demand for high density and fine wire, copper foil, laminated insulating dielectric sh

What materials and classification do pcb circuit boards have?

PCB copper-clad plate is the basic material of electronics industry, mainly used for processing and manufacturing printed circuit board (PCB), and pcb production process and material affect its price

Why should pcb circuit boards do impedance

Impedance refers to the resistance and reactance parameters, because PCB circuit board bottom plug into consideration of electrical conductivity and signal transmission performance, so it is necessary to impedance as low as possible, resistivity should be

Performance test of some common PCBA circuit boards

Kingford is a PCB company engaged in the production and assembly of circuit boards. We not only sell PCBA, but also have many strategies related to PCB design and PCB proofing. Next, let me introduce you to some matters related to PCB.
