Pcb assembly steps in pcb mass production

  1. 1. OurPCB Tech. LTD Add: 3rd Floor, Nanhai Plaza, NO. 505 Xinhua Road, Shijiazhuang, Hebei, China. 050057 Contact: Lillian Yang E: Lillian.yang@circuitspcb.com M: 0086-15511345900 SKYPE: yang.lillian10 PCB Assembly steps in Mass Production PCB Assembly steps in Mass Production Specialized in PCB Assembly for over 10 years, OurPCB is equipped with many advanced machineries, including three high speed SMT lines, Siemens HS50 Pick and placers, Siemens F5 pick and placers, Heller 1809 Reflows, Speedline MPM printers, OK intelligent solder irons, Otek Automatic Optical Inspection and many other advanced machineries. We assemble BGA, LGA, QFN, QFP, DIP, SIP.., the smallest SMT footprint we can mount is 0201. Our factory can also provide programming, wiring as well as injecting and conformal coating services. You can find some important PCB assembly steps below. 1. pcb SMD Assembly Surface mount devices are miniaturized components that are placed directly mounted on the printed circuit board and get soldered on the same side. Before any placement, solder paste is applied to board with respect to pads/connection through stencils. SMD assembly is mostly automated for mass production of PCB Assembly. Common automatic SMT placement machines can place thousands of components per hour, making this part of the assembly highly automated and fast. SMD assembly is an important part in PCB assembly step.

After SMD assembly, inspection of board is performed to rectify any problem. 2. pcb Through-Hole Assembly Through-Hole Assembly is also very important PCB Assembly step. Larger components in through-hole packages are manually placed on PCB. Directional components like capacitors and LEDs are taken proper care in placement and visual/ camera inspection is performed. After inspection, components are soldered to the PCB through wave soldering in automated process or manual soldering in non-automated process.

Testing, Cleaning and Coating Fully assembled board is tested, usually through bed-of-nail tester or flying-probe-tester in order to confirm the functionality of components. After this stage, board is cleaned (usually ultrasonic cleaner) to remove any reside of flux or soldering and then conformal coating is applied to protect the board form any contamination. Now, assembled board is ready to be shipped/ placed inside the product. A typical fully assembled board is shown in the figure 1 below. for more posts, pls visit http://www.ourpcb.com/ in needs of PCB or PCB Assembly Services, feel free to
