The role and difference of solder mask and solder paste layer

The impact of many projects on solder masks and solder layers is unclear. It is to open the window itself, but only provides the paste layer. There is no solder layer. Some board engineers don't look at the paste layer (note that this is used). This is a useless layer for the plant's engineers and can cause window leaks. The following is a brief introduction to their differences. The solder layer is used to control the area where the green oil (white oil) is not covered when the board is fabricated. For example, the position of the pad, [...]

Who Can Benefit From Turnkey PCB Assembly Services?

Advantages of Full Turnkey PCB Assembly Services and Who Can Benefit From Turnkey PCB Assembly Services? • Shorter Lead Time As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey [...]

How to Identify Circuit Board Electronics Components?

How to Identify Circuit Board Electronics Components? Start by identifying the printed circuit board, or PCB. This is the underlying rectangular chip or board, often in green or blue. This chip is covered in conductive pathways--little lines of metal that are actually printed on the board by another machine during production. Notice that each of these lines starts with a dot and is most likely labeled with a number. Though they are not wires, each of these connective lines works in the same manner as a wire to transmit independent lines of electricity. Identify other "nuts and bolts" electronic circuit [...]

The differences between immersion gold and gold plating for bare PCB

Gold plating: Gold plating is a method of depositing a thin layer of gold onto the surface of another metal through plating way. The gold particles attached to the pcb, as strong adhesion also known as hard gold. The gold finger of memory bank is hard gold and abrasion resistant. Immersion gold: Immersion gold through chemical reaction to make gold particles attached to pcb. As weak adhesion it is also known as soft gold. Why use gold plating for some printed circuit board? As IC become more and more integrated and IC pins are also denser. This brings difficulty to [...]

BENEFITS OF CONFORMAL COATING FOR PCB& PCB Assembly

A conformal coating is defined as a thin layer of transparent plastic that "fits" the body of the PCB and component. By being breathable, it forms a protective layer that protects against particular environmental conditions, but also allows any moisture trapped in the board to escape. The conformal coating is a protective coating for printed circuit boards (PCBs). It protects PCB components from moisture, heat, cold, dust, smoke, weather changes and other environmental conditions that can affect PCB performance. The use of a conformal coating on the PCB reduces the need for repair or replacement of printed circuit boards, thereby reducing [...]

Five knowledge points of PCB Design technology–Hitech Circuits Co., Limited

1: Print line width selection: The minimum width of the printed line is related to the current flowing through the line: the line width is too small, the resistance of the printed line is large, and the voltage drop on the line is large, which affects the performance of the circuit. The width, the wiring density is not high, and the board area is increased. In addition to increasing the cost, it is not conducive to miniaturization. If the current load is calculated as 20A / mm 2 , when the thickness of the copper foil is 0.5MM (generally), the [...]

What is the difference between Rogers PCB and ordinary PCB?

Compare with ordinary PCB, Rogers PCB is widely used in high frequency and high reliability fields such as microwave communication, 5G, military radar, etc. Furthermore, Rogers PCB is a high-performance PCB, which means: 1.Good rigidity, mechanical and electrical properties, easy to hole metallization; 2.High precision of board thickness; 3.Awesome copper adhesion, high heat dissipation capacity, perfect peel strength, no layering and foam; 4.Be compatible with FR-4 processing technology except the higher cost of Rogers board itself. PS: Rogers PCB is the most stable material in the industry, with low dielectric loss and low water absorption. In addition, its dielectric constant (DK) is stable with [...]

PCB Manufacturing Process: how are PCBs made

PCB Manufacturing Process: how are PCBs made PCB holes and vias Holes, often called via holes or vias are needed within a PCB to connect the different layers together at different points. Holes may also be needed to enable leaded components to be mounted on the PCB. Additionally some fixing holes may be needed. Normally the inner surfaces of the holes have copper layer so that they electrically connect the layers of the board. These "plated through holes" are produced using a plating process. In this way the layers of the board can be connected. Drilling is then accomplished using [...]

How to Ensure the Quality of Printed Circuit Board and PCB assembly manufacturing

PCBs (Printed Circuit Boards) are the most used and basic PCB assembly unit applied by all types of electronic devices. All functions and performance of devices are implemented mainly by PCBs. Put simply, PCBs are the heart of electronic devices and both their quality and reliability is directly correlated with quality and reliability of electronic equipment. Nowadays, intelligence and miniature of electronic devices leads to increasingly smaller size and complicated structures of PCBs. In terms of PCB performance, it can be testified that even if schematic is correctly designed, subsequent assembly and debugging will still be influenced if PCB design [...]
