QUALITY SYSTEM

The plant is incorporated with ISO9001:2015 certified Quality Management System and using most stable and modern processes and process control techniques and reliable raw material. We are committed to provide the best Electrical Insulation and Electronics Inter connection to fulfill the customer requirements.

FRONT-END MANUFACTURING

The first critical step in our production process, where we verify that all design data is accurate and ready for fabrication. This ensures your PCB is built exactly to specifications from the very start.

PRINTING AND PRE-ETCHING COPPER INSPECTION

PCB circuit printing is a fragile step while manufacturing of electronic devices, involving the transfer of circuit patterns onto a copper-clad board. This at DHAN is done using screen printing. Before the etching process, a thorough pre-etch copper inspection is essential to ensure there are no defects such as scratches, oxidation, or contamination on the copper surface that could affect the accuracy of the circuit paths. This inspection helps identify any issues that might compromise conductivity or lead to short circuits, ensuring high reliability and performance of the final PCB.

POST ETCH COPPER INSPECTION

Post-etch copper inspection in PCB manufacturing is a crucial quality control step conducted after the unwanted copper has been removed from the board. This process ensures that the remaining copper traces accurately match the intended circuit design, with no under-etching, over-etching, or residual copper that could cause shorts or open circuits. Inspectors check for issues such as incomplete etching, line width variations, and surface contamination. This ensures that the PCB meets stringent electrical and dimensional standards before advancing to subsequent production stages

DRILLING

Our drilling equipment is equipped with automated verification systems that continuously monitor and check drill diameters to ensure all holes conform precisely to specified measurements. This process guarantees high accuracy and consistency, reducing the risk of defects and ensuring compliance with design and quality standards.

BBT Process And Final QC

The Bare Board Testing (BBT) process is done right before our Final Quality Check and packing. This ensures that each PCB is tested for continuity and isolation which thereafter leads to no open circuits or unintended shorts between conductive paths. The FinalQuality Control (Final QC) process is conducted to inspect the board’s overall quality. This includes visual and dimensional checks, solderability testing, surface cleanliness, and confirmation that all markings and specifications meet customer requirements. Together, BBT and Final QC ensure that only defect-free, fully functional boards proceed to our customers , maintaining high reliability and performance in end-use applications.
