SMT assembly Processing / Patch Processing Basic Process Elements

The basic process elements of smt assembly 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 [...]

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 [...]

Electronics assembly manufacturing–Why Use Reflow Soldering?

Electronics assembly manufacturing 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 Electronics assembly 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 [...]

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 [...]

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 [...]
