What is a high Tg PCB board and the advantages of using high Tg PCB

When the temperature of a high Tg printed board rises to a certain area, the substrate will change from “glass state” to “rubber state”, and the temperature at this time is called the glass transition temperature (Tg) of the board. In other words, Tg is the highest temper... Read More

The role of FPC flexible circuit board solder mask

In the circuit board production, the green oil bridge is also called the solder mask bridge and the solder mask dam. It is a “isolation band” made by the circuit board factory to prevent the short circuit of the pins of SMD components. If you want to control the FPC soft board (FPC fl... Read More

Aluminum substrate pcb use: power hybrid IC (HIC). 1. Audio equipment Input and output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc. 2. Power equipment Switching regulator, DC/AC converter, SW regulator, etc. 3. Communication electronic equipment The hig... Read More

The difference between aluminum substrate and glass fiber board

The difference and application of aluminum substrate and glass fiber board 1. Fiberglass board (FR4, single-sided, double-sided, multilayer PCB circuit board, impedance board, blind buried via board), suitable for computers, mobile phones and other electronic digital products. There are many ways... Read More

Factors of poor tin on PCB and prevention plan

The circuit board will show poor tinning during SMT production. Generally, poor tinning is related to the cleanliness of the bare PCB surface. If there is no dirt, there will be basically no bad tinning. Second, tinning When the flux itself is bad, the temperature and so on. So what are the main ... Read More

What are the advantages, applications and types of aluminum substrates

Aluminum base plate (metal base heat sink (including aluminum base plate, copper base plate, iron base plate)) is a low-alloyed Al-Mg-Si series high plastic alloy plate, which has good thermal conductivity, electrical insulation performance and mechanical processing performance. Compared with the... Read More

The difference between leaded process and lead-free process of pcb

PCBA and SMT processing generally have two processes, one is a lead-free process and the other is a leaded process. Everyone knows that lead is harmful to humans. Therefore, the lead-free process meets the requirements of environmental protection, which is a general trend and an inevitable choice... Read More

Differences in characteristics between FPC and PCB

In fact, FPC is not only a flexible circuit board, but it is also an important design method of integrated circuit structure. This structure can be combined with other electronic product designs to build a variety of different applications. Therefore, from this point on Look, FPC and hard board a... Read More

FPC Application Field

FPC applications MP3, MP4 players, portable CD players, home VCD, DVD, digital cameras, mobile phones and mobile phone batteries, medical, automotive and aerospace fields FPC has become an important variety of epoxy copper clad laminates. It has flexible functions and is epoxy resin. The flexible... Read More

The design points of the hard-soft fusion board of pcb circuit board

1. For power circuits that must be repeatedly bent, it is best to choose a single-sided soft structure, and choose RA copper to improve fatigue life.  2. It is proposed to maintain the inner electrical layer wiring of the bonding wire to bend along the vertical direction. But sometimes it cannot ... Read More

Five requirements for pcb imposition

In order to facilitate the production and manufacture, PCBpcb circuit board jigsaw generally must design the Mark point, V-groove, and processing edge.  PCB appearance design 1. The frame (clamping edge) of the PCB splicing method should adopt a closed-loop control design scheme to ensure that th... Read More

Is circuit board PCBA cleaning really important?

“Cleaning” is often ignored in the PCBA manufacturing process of circuit boards, and it is considered that cleaning is not a critical step. However, with the long-term use of the product on the client side, the problems caused by the ineffective cleaning in the early stage cause many ... Read More
