Introduction to PCB double-sided reflow process (SMT)

Introduction to PCB double-sided reflow process (SMT) Circuit board assembly technology, now popular in the industry is full-board reflow soldering (Reflow), this technology can be divided into single-panel reflow and double-panel reflow. Single-sided reflow is used less because double-sided reflow saves board space. Double-sided reflow requires two reflows. Because [...]

What is the difference between PCB and PCBA?

I believe that many people are no strangers to PCB boards. They may be heard frequently in daily life, but they may not know much about PCBA and may even be confused with PCB. So what is a PCB? How did PCBA evolve? What is the difference between PCB [...]

Analysis of the pcb soldering defects

Analysis of the pcb soldering defects There are three main factors that cause pcb soldering defects: First, the solderability of the hole affects the pcb soldering quality Circuit board hole solderability is not good, will produce solder defects, affecting the circuit components of the parameters, resulting in multi-layer board [...]

Design Rule Check (DRC)

After the wiring design is completed, it is necessary to carefully check whether the wiring design meets the rules set by the designer, and also needs to confirm the formulation. Whether the rules meet the requirements of the printed board production process, the general inspection has the following aspects: [...]

Double sided metal core pcb

Double sided metal core pcb It also has same two layers of copper conductor like Double layers MCPCB, but the metal core is in the middle of two conductor, so there're conductors (trace) on both sides of metal core, and were connected to each other by Vias. So [...]

The difference and advantages and disadvantages of gold plating and immersion gold process

The difference and advantages and disadvantages of gold plating and immersion gold process (1) Why use gold-plated plates As ICs become more integrated, the IC pins are more dense. The vertical tin-spraying process is difficult to flatten the fine pads, which makes the placement of the SMT difficult; in [...]
