PCB Manufacturing and PCB Assembly Step-by-Step Guide for Electronic Assembly process

Printed Circuit Board or PCB’s are an integral part of every electronic device. They are the green chips that you can find within all electronic devices. These green chips or Printed Circuit Boards are printed with copper lines called traces, which carry signals to various components. This systematic transmission of signals ensures the proper functioning of the electronic device. PCBs are omnipresent in every modern day electronic device. As the technology advances and the electronic devices becoming more and more compact, there is a drastic reduction in the size of the PCB. This reduction in size increases the complexity of [...]

The Definition and Features of HDI PCB (High density pcb)

High-Density Interconnection (HDI) board is one of the key technologies driving advancements in PCB electronics. Through its multiple via processes, HDI technology minimizes the number of layers, making for smaller yet more powerful PCB circuitry. Definition HDI, or High-Density Interconnection, is a PCB technology that emerged around the end of the 20th century. The advantages it holds over the traditional PCBs fueled its popularity tremendously. HDI PCB by laser drilling technology. That precludes the drawbacks you face when using the traditional mechanical drilling technology, including higher cost and improvement difficulties. HDI PCB fabrication deploys advanced multilayer technology [...]

DESIGNING FLEXIBLE PRINTED CIRCUIT BOARDS (Part Two)

High-density-Interconnect (HDI) Flexible PCBs When there are no adequate options provided by typical flexible circuits, HDI PCBs come into play by incorporating fine features like micro-vias, better layout, construction, and design. In addition to the above features, other features include; highly dense flex circuitry, Increased functionality, and smaller form factor. HDI technology offers improved electrical performance, access to advanced IC package use, and better reliability though it makes use of thinner materials. Benefits of Flex Circuits As for a ribbon cable or discrete wiring replacement, customized repeatable routing supplied by flex circuits trails all through the assembly. Because of [...]

PCB manufacturing-What Is Trace Impedance

In printed circuit boards, wires and traces are typically formed from copper because it is the least-resistant element apart from silver. Put an ohm meter over a trace and the DC resistance is almost negligible. The same cannot be said of AC impedance. Impedance, unlike resistance, is based on frequency. All wires and traces will generate at least some impedance to current flowing from any driver. While, usually, you must have a fairly fast rise time for your signals for trace impedance to become a problem, it’s important that you be aware that trace impedance exists and can become an [...]
