SMT Processing Plant Equipment: Complete Guide to SMT Line Setup What Is an SMT Processing Plant? An SMT processing plant is a factory facility that assembles printed circuit boards with SMT PCB assembly technology. Surface mount components are placed directly onto pads on the board and soldered in place, which…

False Soldering in PCBA: Causes, Prevention and Rework Guide What Is False Soldering in PCBA? False soldering, also called cold soldering or a cold solder joint, is a condition in which a component appears to be correctly attached to the board but the solder has not formed a real metallurgical…

Via Capping PCB Guide: POFV Process, Benefits and Cost What Is Via Capping on a PCB? Via capping, also called plated over filled via (POFV) or via cap plating, is a PCB fabrication technique in which a drilled and filled via is covered with a thin electroplated copper layer so…

Resin Filled Via PCB Guide: Process, Benefits and Cost What a Resin Filled Via Is A resin filled via is a plated through hole that has been completely packed with insulating epoxy instead of being left hollow. Vias are the vertical tunnels that connect the layers of a multilayer board,…

SMT Placement Accuracy and Machine Maintenance Guide SMT placement accuracy depends on the CAD library, component placement rules, machine calibration, and maintenance. A component cannot be placed correctly if its footprint is wrong or if the placement machine is not aligned. Accuracy must be planned during design and protected during…

SMT solenoid valve maintenance and PNP Camera Maintenance Guide SMT solenoid valve maintenance and PNP camera calibration keep a placement machine accurate and reliable. The solenoid valve controls the compressed air used by cylinders, vacuum nozzles, and other moving parts. The PNP camera system positions components and reads fiducial marks.…

ICT in-circuit testing PCBA : Needle Bed Guide | gopcb ICT in-circuit testing for PCBA is a contact test method used to check manufacturing defects and defective components by testing the electrical connections and power behavior of online components. ICT has strong fault diagnosis capability and is widely used in…

SMT Machine Sensors and Tool Change Guide SMT machine sensors allow a pick-and-place machine to detect position, pressure, and safety conditions during every placement cycle. The sensor system is an important part of the whole SMT machine. Without sensors working together, the placement system cannot assemble boards reliably or safely.…

PCBA Quotation Process: Complete Pricing Guide The PCBA quotation process is a structured workflow used by customers and electronics manufacturers to agree on the price of PCB assembly. A good quotation process varies from one customer to another, but there are standard requirements that should be followed in every high-quality…

PCBA Component Damage Analysis: Crack and Stress Guide PCBA component damage analysis helps engineers find out why a surface mount component cracked, lifted, or failed during assembly. As electronic products become more densely packed, the number of components on a single board increases and the risk of damage also increases.…
