The so-called metalized half-hole means that after a drilling (drilling, gong groove) is drilled, and then drilled, the shape process, and finally half of the metalized hole (groove) is retained. In order to control the production of metal half-hole boards, some measures are usually taken due to process problems at the intersection of metalized half-holes and non-metalized holes. In the current saturated state of circuit board proofing factories, there are not many board factories willing and able to produce half-hole boards.
PCB, which simply means Printed circuit board lays a good foundation in modern electronics technology. Its indispensability is seen in its applications for the development of various electronic products. One of such products commonly used nowadays is LED PCB.
A gadgets high-recurrence execution depends vigorously on the electrical properties of the PCB utilized for mounting and associating its circuit parts. The degree of the PCB configuration impact heightens dramatically with an increment in functional recurrence.
PCBA testing mainly includes five forms: ICT testing, FCT testing, Burn In Test, Fatigue Test, and Severe Conditions Test: The ICT (In-Circuit Test) test mainly includes circuit continuity, voltage and current values, fluctuation curves, amplitude, noise, etc., and does not involve function keys or input and output tests.Some like AOI test,X-ray test. PCBA testing image.png For FCT (Functional Test) testing, you need to first burn the prepared microcontroller (MCU) program into the program IC through a burner (such as ST-Link, JTAG) to simulate the function of the entire PCBA board, such as after pressing a button , The LED light is on; press the two buttons at the same time to restore the factory settings and so on. So as to find out the problems in the hardware and software, and equip with necessary patch processing production jigs and test racks.
PCB’s whole name is Printed Circuit Board or PWB(Printed Wire Board),It’s the support of electronic components and the carrier of electrical connection of electronic components.Like below: PCBA’s whole name is Printed Circuit Board Assembly.Like below: PCBA When you need do PCBA,you’d better send gerber data,PCB spec and BOM(Bill of Material:see blow) to factory.
The production process of PCB is more complicated, and it involves a wide range of processes, from simple mechanical processing to complex mechanical processing, common chemical reactions, photochemical, electrochemical, thermochemical and other processes, computer-aided design CAM, and many other aspects of knowledge . Moreover, there are many process problems in the production process and new problems will be encountered from time to time. Some of the problems disappear without finding out the cause.
Without a doubt, you will agree that printed circuit boards, commonly referred to as PCB are among the components of various electrical appliances with so much impact in how their appliances serve us. Right from the largest as well as the most sophisticated of various electrical units such as those found in the control panel of airplanes and automobiles to those found in the smallest electrical devices such as children toys, we can say that PCB have added so much flavor to life as far as electrical devices are concerned.
Victory is a professional PCB manufacturer which established in 2005. Adhere to be a specialized manufacturer for multiply species, small to medium series, and quick turn production, we insist to provide 3H(high quality, high precision and high density) PCBs to our customers.
Immersion gold plating is an interaction that applies an extremely slim layer of gold by dislodging the surface molecules. This implies the covering isn't extremely thick, ordinarily somewhere in the range of three and eight miniature inches.
If a PCB includes three or more layers or sheets of copper foil that are isolated from each other coating) and linked together to form a single component, it is called a high-density multilayer PCB. It must have at least three layers of conductive material buried in the material's center.
The printed circuit board (PCB) manufacturing process requires a complex procedure to ensure the performance of the finished product. Though circuit boards can be single, double or multilayered, the fabrication processes used only differ after the first layer’s production. Due to differences in the structure of the PCBs, some may require 20 or more steps during manufacturing.
Printed circuit boards (PCBs) have been an integral part of electronics for many years. Through the years, electronic devices are getting smaller and more complex and so are the PCBs needed to connect the components in an efficient manner. As robotics and electronic design begin to be taught as early as grade school, the art of PCB layout becomes more meaningful. What follows are 5 common myths about PCB layout:
