Why Use Reflow Soldering?

Reflow soldering allows for the simultaneous processing of multiple connections. This prevents the disconnection of wires while you are soldering their neighboring wires. Reflow Soldering also improves the quality of resulting PCB and offers many other benefits such as, Improved wettability of solder joints and surface mounted components. Improved solderability of a large variety of electronic components. Enhanced joint integrity for crucial electronic applications. Reduced board discoloration. Elimination of charred flux residues on heating elements and boards. Reduced formation of white haze from the oxidation of rosin or tin flux Optimized performance of low-residue and no-clean pastes. Enhanced flexibility of [...]

How to Decrease the PCB Assembly Cost

With improving technologies, the cost of every production is increasing. Profit margins are being raised. When you look for quality products for your application, the costs are likely to be even higher. But, you obviously want to reduce spending on your expenses, without compromising on the quality. Is that even possible? Electronics companies are always facing issues while attempting to cut down costs as the technology is constantly changing. Electronic devices are always evolving into more and more complex products, in order to meet consumer demands. This is why technology companies are evolving to find new processes for developing products [...]

Specifications for the manufacture of aluminum base PCB

The aluminum boards produced by PCB manufacturers are mostly used for LED lamps. What are the specifications for the production of aluminum base board in the production process? Aluminum boards produced by aluminum board manufacturers are often used in power devices, and the power density is large, so the copper foil is relatively thick. If a 3 oz or more copper foil is used, the etching process of the thick copper foil requires engineering line width compensation, otherwise, the line width after etching will be excessive. The surface of the aluminum boards produced by the aluminum board manufacturer must be protected with a protective [...]

What are the advantages of HDI PCB technology-Hitech PCB

HDI stands for High Density Interconnector. A circuit board which has a higher wiring density per unit area as opposed to conventional board is called as HDI PCB. HDI PCBs have finer spaces and lines, minor vias and capture pads and higher connection pad density. It is helpful in enhancing electrical performance and reduction in weight and size of the equipment. HDI PCB is the better option for high-layer count and costly laminated boards. Following is the advantages for the HDI PCB. This technology allows future components, that are becoming smaller, to be used on a wider scale. Electrical [...]

How to prevent your PCB from overheating

Green printed circuit board (PCB) Printed circuit board (PCB) materials are formulated to withstand a certain amount of heat. What happens when the temperatures rise beyond certain limits? Performance takes a nose dive, especially at higher frequencies. This is why cost-effective heat management is perhaps an engineer’s number-one priority. Of course, heat-tolerant PCB materials and carefully designed circuits can tolerate a certain amount of heat. First, the circuit designer should understand the different parameters of the materials’ behavior when temperatures rise. Heat comes from various sources Circuit boards are assembled in increasing density to make smaller, lighter designs. A [...]

SMT Processing / Patch Processing Basic Process Elements

The basic process elements of smt processing / patch processing: Silk Screen (or Dispensing) --> Mounting --> (Curing) --> Reflow Soldering --> Cleaning --> Testing --> Rework Silk screen: Its function is to print solder paste or patch glue on the pad of PCB to prepare for soldering of components. The equipment used is a screen printing machine (screen printer), located at the forefront of the SMT production line. Dispensing: It is a glue that drops the glue to a fixed position on the PCB. Its main function is to fix the components to the PCB. The equipment used is [...]

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 [...]
