Eight common problems and solutions in PCB design

In the process of PCB design and production, engineers not only need to prevent accidents during PCB manufacturing, but also need to avoid design errors. This article summarizes and analyzes these common PCB problems, hoping to bring some help to everyone’s design and production work.  ... Read More

PCB printing process advantages

From PCB World.   Inkjet printing technology has been widely accepted for the marking of PCB circuit boards and solder mask ink printing. In the digital age, the demand for instantaneous reading of edge codes on a board-by-board basis and instant generation and printing of QR codes has made ... Read More

Thailand occupies 40% of Southeast Asia’s PCB production capacity, ranking among the top ten in the world

From PCB World.   Supported by Japan, Thailand’s automobile production was once comparable to France’s, replacing rice and rubber to become Thailand’s largest industry. Both sides of Bangkok Bay are lined with automobile production lines of Toyota, Nissan and Lexus, a boiling sc... Read More

The difference between PCB schematic and PCB design file

From PCBworld When talking about printed circuit boards, novices often confuse “PCB schematics” and “PCB design files”, but they actually refer to different things. Understanding the differences between them is the key to successfully manufacturing PCBs, so in order for be... Read More

About PCB baking

  1. When baking large-size PCBs, use a horizontal stacking arrangement. It is recommended that the maximum number of a stack should not exceed 30 pieces. The oven needs to be opened within 10 minutes after baking to take out the PCB and lay it flat to cool it. After baking, it needs to be presse... Read More

Why do expired PCBs need to be baked before SMT or furnace?

The main purpose of PCB baking is to dehumidify and remove moisture, and to remove the moisture contained in the PCB or absorbed from the outside, because some materials used in the PCB itself easily form water molecules. In addition, after the PCB is produced and placed for a period of time, the... Read More

Fault characteristics and maintenance of circuit board capacitor damage

First, a small trick for multimeter testing SMT components Some SMD components are very small and inconvenient to test and repair with ordinary multimeter pens. One is that it is easy to cause a short circuit, and the other is that it is inconvenient for the circuit board coated with an insulatin... Read More

Remember these repair tricks, you can fix 99% of PCB failures

Failures caused by capacitor damage are the highest in electronic equipment, and damage to electrolytic capacitors is the most common. The performance of capacitor damage is as follows: 1. Capacity becomes smaller; 2. Complete loss of capacity; 3. Leakage; 4. Short circuit.   Capacitors play... Read More

Purification solutions that the electroplating industry must know

Why purify?   1. During the use of electroplating solution, organic by-products continue to accumulate 2. TOC (Total Organic Pollution Value) continues to rise, which will lead to an increase in the amount of electroplating brightener and leveling agent added 3. Defects in the electroplated ...

Copper foil prices are rising, and expansion has become a consensus in the PCB industry

Domestic high-frequency and high-speed copper clad laminate production capacity is insufficient.   The copper foil industry is a capital, technology, and talent-intensive industry with high barriers to entry. According to different downstream applications, copper foil products can be divided... Read More

What are the design skills of op amp circuit PCB?

Printed circuit board (PCB) wiring plays a key role in high-speed circuits, but it is often one of the last steps in the circuit design process. There are many problems with high-speed PCB wiring, and a lot of literature has been written on this topic. This article mainly discusses the wiring of ... Read More

You can judge the PCB surface process by looking at the color

here is gold and copper in the circuit boards of mobile phones and computers. Therefore, the recycling price of used circuit boards can reach more than 30 yuan per kilogram. It is much more expensive than selling waste paper, glass bottles, and scrap iron. From the outside, the outer layer of the... Read More
