Surface Mount PCB Assembly Services
Surface Mount (SMT) PCBs have gained immense popularity in the recent years, owing to several beneficial features they offer. These PCBs are compact sized, and they perfectly meet the growing demand for miniature electronics. At DML Electronics, we have over 20 years of experience in delivering the highest quality SMT assembly services. In these circuit boards, the components are directly mounted on the PCBs. We utilize several fully automated equipment to accurately position the components on the PCB. Our unwavering commitment to quality has helped us deliver SMT PCB assemblies, which are known to offer consistent performance for a long time.

Stencil Printing Machine
Flexible Component Placement Systems Reflow Ovens Rheometer ( for adhesives, solder pastes, and epoxy analysis) Wave Soldering Systems Acoustics Scanning Microscopes ( for crack and void checking) Microscopy X-ray Inspection Machine Vitronics Reflow Ovens In-line Aqueous Cleaners
Testing and Inspection
Every PCB manufactured at our facility undergoes rigorous testing and inspection. We assure 100%  AOI (Automated Optical Inspection) of Surface Mount Assemblies. We employ the following evaluation process to ensure the highest quality of the PCBs.
Vibration and Shock Testing
Scanning Electron Microscopy (SEM)
Cross-sectioning, Specimen Preparation and Evaluation
Humidity and Temperature Testing
Environment Chamber
Humidity and temperature are the two factors that may have a negative impact on the assembly process. Thus, we tightly monitor and control these processes inside our facility to minimize their impact. We also take precautions to protect the sensitive electronic components on the printed circuit board from ESD (Electrostatic Discharge).
