In the ever-evolving world of electronics, one component stands out as a fundamental building block: the Rigid Printed Circuit Board (PCB). These unassuming green or brown boards are Read More

Adding text and identifiers to PCBs is essential for board identification and component marking. This is done using a silk screen generated by PCB design software after the board's main manufacturing processes are complete. Standard colors include green, black, white, and yellow, with non-standard options available at higher costs. Legend printing methods include manual screen-printing for larger line widths, Liquid Photo Imaging (LPI) for higher accuracy, and Direct Legend Printing (DLP) for maximum precision but at greater expense. Designers must follow IPC requirements for manufacturer marks and should avoid placing legends over circuit pads. Ensuring proper alignment, color selection, and considering manufacturing tolerances can help reduce costs. Read More

Printed Circuit Boards (PCBs) are typically made from a fiberglass epoxy resin substrate with copper foil on one or both sides. More affordable PCBs use a phenolic resin substrate, commonly found in household electrical devices. PCB design is facilitated by software like Eagle, allowing for the quick creation of a circuit pattern. The process involves printing the design on transparent paper, transferring it to a photo-resist PCB using ultraviolet light exposure, and developing the design using a developer solution. The board is then etched with a ferric chloride solution to remove excess copper, leaving the desired copper traces intact. Finally, holes are drilled in the board using a CNC machine or manual tools to complete the PCB, making it a cost-effective and efficient method for DIY electronic projects. Read More

Advances in PCB design software have made PCB creation accessible to more people, and online searches can help users find manufacturers, particularly in China, which is the world's largest PCB production base. Shenzhen, a key electronics hub in China, hosts numerous companies capable of quickly designing, manufacturing, and supplying PCBs. Online research is crucial when purchasing PCBs or PCB assemblies (PCBA), as pricing varies among companies. Instant quotes from providers like SysPCB in Shenzhen can help ensure customers receive the desired PCB at a competitive price. Read More

For PCB quotations, while simple single-sided or double-sided PCBs can be roughly estimated using PDF or JPG files, it is challenging to provide accurate quotes for complex multilayer PCBs with more than four layers. PDF and JPG formats are insufficient for PCB fabrication, as only PCB format files or Gerber files are suitable. If PCB files are unavailable, PCB samples can be used to generate Gerber files. PCB designs should be created using common software like Protel DXP, Powerpcb, or PADS, and the files must be in formats such as PCB, ODB, Gerber, or DWG. Additionally, specifications like board thickness, copper thickness, solder mask color, and surface treatment must be provided for accurate quotations or production. It's also important to verify the manufacturing capacity of the PCB provider to avoid potential production issues. Read More

PCB manufacturers often face challenges when customers request quotations based on PDF or JPG files, which are inadequate for accurate pricing of complex multilayer PCBs and cannot be used for fabrication. Accurate quotations and fabrication require PCB format files or Gerber files generated by common design software like Protel DXP, Powerpcb, or PADS. Manufacturers also need detailed PCB specifications, including board thickness, copper thickness, solder mask color, and surface treatment. If PCB files are unavailable, manufacturers can create Gerber files from physical PCB samples for production. Read More
