Common Soldering Defects and How the Process Prevents Them Most soldering defects are not mysterious. They appear in recognisable forms, they have a limited number of causes and the causes are almost always upstream of where the defect becomes visible. The difficulty is not in understanding the mechanism but in…

Aging Test and Burn-in for Industrial PCBA A board that passes its functional test on the day it is built has demonstrated that it works, not that it will continue to work. The distinction matters most for industrial, medical and automotive products, where the equipment is expected to run for…

PCB Component Storage Conditions: Keeping Parts Ready to Use Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB component storage conditions from the perspective of a PCBA factory…

PCB Cleaning After Assembly: Residue, Cleanliness and Coating Whether an assembled board has to be cleaned is a decision that belongs to the product rather than to the process, and making it by default in either direction causes problems. Cleaning a board that did not need it adds an operation,…

PCB Feeder Setup and Reel Loading: Design and Assembly Considerations Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB feeder setup and reel loading gives you…

PCB Placement Force Control: Process Details and Inspection Points Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article…

Functional Test and Test Fixture Development for PCBA An assembly that has been built correctly does not necessarily work, and a product that works does not necessarily work within its specification. The functional test is the stage that answers the second question, and it is the last opportunity to prevent…

PCB Component Centring Vision: Seeing Where the Part Is Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB component centring vision gives you a practical advantage…

Scaling a Verified Design into Volume Manufacturing There is a point in every hardware programme where the design stops being a project and becomes a product, and that point is not the design freeze. It is the moment the design is released into volume manufacturing, where the boards are built…

BOM Procurement and Material Control in Contract PCBA Manufacturing Contract manufacturing with material included is described as a turnkey arrangement, and the part of it that actually determines the schedule is the BOM procurement behind the assembly. A customer who supplies the boards and the parts buys a process; a…
