PCB Assembly Services

As one of the leading PCB assembly manufacturers, Suntronic follows a thorough process to produce high-quality and performance-driven assembled PCBs. Under Suntronic’s PCB assembly services, we follow the following steps.

• Material and Component Procurement: After seeking client approval, our team chooses high-quality material and components procurement. This step helps us ensure the availability of quality components before the start of the assembly process. High-quality materials help us assure performance-centric electronic assembly services.
• Solder Paste Application/ Stenciling: In this step, the actual PCB fabrication process begins. No matter what type of PCB is being fabricated, stenciling remains the primary step. In this step, we apply a stencil to the board. This is then followed by the application of solder paste. This ensures that the solder paste is applied only where the components are to be mounted.
• Component Mounting: We opt for pick and place component mounting operation under conventionally-led surface mount technology. In the automated PCB fabrication, we adopt pick and place component mounting by using robotic arms. This helps in rapid component mounting and reduces the chances for human errors. Our advanced automated component mounting capabilities allow us to satisfy complex PCB assembly requirements such as BGA, UBGA, CSP, etc. Automation of component mounting applications reduces the duration of the production cycle and enhances the efficiency of our electronic assembly services.
• Soldering: All mounted components are fixed in place using selective wave soldering. In this process, a solder material or filler material like lead/tin is filled at the joining points of components followed by furnace heating and natural cooling. This fixes the component at the mounted location. We also offer lead-free soldering.
• Conformal Coating: The PCBs are secured using a suitable conformal coating material. This helps protect the copper on PCBs from oxidation.
• Inspection and Testing: Inspection and testing is the post-production step we adopt at Suntronic. Being one of the most quality-centric PCB assembly manufacturers, we are focused on the quality and performance of our custom PCB manufacturing services. Therefore, we go for inspection and testing methods as follows.
• Functional Testing
• Durability Testing
• Visual and Advanced Inspection

Note: All the above-mentioned steps are part of the standard procedure we follow under our PCB assembly services, however, the production parameters may vary based on customization requirements.
