Why we discuss secret of Boundary Scan Some customers ask Emma the question about Boundary scan. This is a professional PCBA glossary, and most new PCB guys don’t know. Then 4MCPCB experts want to share more PCB and PCBA technology. We want to let more friends know boundary scan technology. Boundary scan is a method […]

Why we need border data? Now most of PCB manufacturers will design working Gerber file. If you have reviewed some working Gerber files, you will find that almost added some tool border or holes. In our PCB professional glossary called border data. Border Data definition Patterns that appear in the border area, such as tooling […]
In this paper, we are going to discuss some skills of PCBA engineers should be known. May some friends say, as a PCB manufacturer should be introduce more multilayer PCB technology. In fact, most PCBA engineers know little PCB manufacturing technology. PCBA is short for Printed Circuit Board Assembly. The definition of Component Body In […]
The Definition of PCB Board Thickness The overall thickness of the base material and all conductive materials deposited thereon. From this definition, we know different layer PCB board have differing PCB board thickness. The different of PCB board thickness with the copper weight In normal person’s eye, most of them there can equal volume. But […]
You should know PCB board density PCB board density is a very professional PCB glossary. In some PCB design theory, PCB board density is high end definition. This means that most of new PCB designers don’t know this PCB density. Then 4MCPCB have summarized a series article about basic PCB glossary. The definition of PCB […]
Why we discuss Blutter Coat of basic copper This is very little basic copper definition. That’s the reason why most new PCB designers don’t know Blutter Coat. Frankly, Emma also don’t this professional PCB glossary. The definition of Blutter Coat of basic copper An external layer of resin over the reinforcing structure of base material. […]
Bluetooth technology introduces Bluetooth is a short-arrange connectivity technology. It’s according 2.4GHz wireless connectivity standard. And wide applicant in wireless personal area networks (also named PANs). The applications of Bluetooth technology These panels can be used to exchange data between devices such as cell phones, digital cameras, printers and household appliances at data rates of […]
The definition of Blow Hole Below hole is a type void in the solder fillet. And the below hole caused by outgassing from the barrel of a plated through hole. Then the question is what is outgassing. What is Outgassing? If you have learned PCB design theory, you may find the definition of outgassing is […]
Why so many PCB guys don’t know Biscuit Frame? There were several reasons resulting in few of PCB guys know Biscuit Frame. The main reason is that this is a work using in the PCB manufacturing process. Specially in PCB design or run process. The definition of Biscuit Frame An array of circuits on a […]
What is BGA? BGA is short for Ball Grid Array. Most of rigid PCB engineers prefer use BGA. So if you communicate with your a engineer of PCB supplier, you should use BGA. BGA technology introduces Not every rigid PCB board has used BGA technology. In fact BGA technology is a special PCB manufacturing technology. […]
