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.

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.

PCB Assembly Technologies

We maintain product quality consistency and conduct regular upgrades to stay current on the latest tools and machinery. Our customer retention rate is high and the in-warranty rejection rate for any sort of assembly defects has been below 0.7%.

We perform a series of extensive tests and inspection processes on our builds to ensure the highest quality standards.

  1. Flying Probe Testing: We use it for low-volume and prototype circuit boards due to its ease of use in programming to validate line setup without additional cost and time. Our qualified testing team provides you high-fault coverage benefits in a quick turnaround time.
  2. ICT Testing: We use it on mature products for detecting parametric failures, design-related faults, and component failures. ICT Testing takes lesser time to perform when compared to Flying Probe Testing.
  3. Functional Testing: We perform this at the last stage of manufacturing on the finished products before they are shipped. We validate the PCB behavior, its functionality, features to keep it defect-free.
