PCB Assembly Technologies

There are three methods to construct a printed circuit board assembly.

  1. Surface Mount Technology (SMT) – SMT is the process of mounting the electrical components directly on the PCB surface. Leads are soldered on PCB surface directly instead of using hole mounting. We are known for our accuracy and follow the right SMT techniques to yield best-in-class SMT PCB assembly for electronic devices of all sizes. SMT is beneficial where there is limited space.
  2. Through Hole Technique – We provide end-to-end Through-hole assembly services from prototype stage to production. We adhere to international standards and our services comprise both manual techniques for handling complex assemblies and automated techniques for small-volume production. THT provides strength to the components using the state-of-art wave soldering method.

    SMT and THT Assembly capabilities include –

    • Full Through-hole Assembly Line
    • Low to High Volume Production Assembly
    • ESD Controlled Area
    • Single and Double-sided Assembly
  3. Mixed Technology – We render mixed assembly services with Surface Mount Technology (SMT) performed first followed by Through-Hole-Technique (THT). We ease the process in mixed assembly technology by selecting the optimal blend of layout and raw materials.
