Difference between Copper PCB and Standard PCB

Standard PCBѕ uѕе a diеlесtriс and сорреr аѕ thеir mоѕt рrоminеnt mеtаl соnѕiѕt of different lауеrѕ оf material. They fеаturе a ѕubѕtrаtе, оr bаѕе, made frоm fiberglass, роlуmеrѕ, ceramic or аnоthеr nоn-mеtаl соrе. Mаnу оf thеѕе PCBѕ uѕе FR-4 for thе substrate. Thiѕ fibеrglаѕѕ mаtеriаl has a rеlаtivеlу affordable price аnd mоdеrаtе durability. Additiоnаl layers of copper, ѕоldеr mаѕk and ѕilkѕсrееn make the bоаrd conductive and outline соmроnеnt lосаtiоnѕ.

Printed Circuit Board industry accelerates transfer to China

The industry moves eastward and the mainland is unique. The focus of the PCB industry is constantly shifting to the Asian region, and Asia's production capacity is further transferred to the mainland, forming a new industrial structure. With the continuous transfer of production capacity, mainland China has become the region with the highest PCB production capacity in the world.   Applications such as data centers will increase HDI demand, and FPC will have broad prospects. Data centers are moving in the direction of high speed, high capacity, cloud computing and high performance, and construction demand is exploding. The demand for [...]

Automated Optical Inspection (AOI)

Automated Optical Inspection (AOI) is the automated visual inspection of a Printed Circuit Board (PCB) in which a camera is used to scan the board in extremely fine detail to check for any defects or failures. So why is AOI so important? Assuming your PCB design is correct, if you assemble the right parts in the right place then your product will work. In production, this means putting a lot of focus on detecting and correcting any manufacturing defects or Manufacturing Defects Analysis (MDA.) AOI is a vital inspection system which enables you to measure and monitor the quality of [...]

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 [...]

What Function Does PCB Board Offer for Electronic assembly manufacturing Products?

Whether PCB circuit boards, aluminum PCB or single-sided PCB,they all have a common name, that is a printed circuit board (PCB) or printed wireless board (PWB), then what function does PCB board offer for electronic assembly products. The function that PCB boards provide for electronic assembly products 1. Assurance integrated circuits and other electronic components fixed, and support mechanical assembly  . 2. Ensure the quality of the electronic equipment, improve the labor productivity, reduce the cost and easy to maintenance. 3. Provide resistance welding graphics for automatic soldering,provide identification of characters and graphics for components instrumentation, inspection, maintenance. 4. Implementation electrical connections or [...]

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 [...]
