LGA Soldering and RF Test on a Positioning Terminal Board A positioning terminal board may start up and communicate normally and still take too long to acquire satellites, receive a weak signal or report an unstable position. Taking the module off the board at that point is a common reaction…

PCB Solder Ball Inspection: 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…

PCB BGA Voiding: A Practical Review for Manufacturing Teams 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 BGA voiding gives you a practical advantage when…

Moisture Sensitive Device Management for Meter Boards A smart meter communication board carries a main controller, a wireless module, memory, isolation devices and power conversion, and a proportion of the soldering problems that appear on such a board do not originate in the reflow oven at all. When an integrated…

FPC Connector Assembly on Commercial Printer Boards A commercial printer control board connects to a display panel, sensors, a scanning assembly, motors and an operating keypad, and several flexible printed cable connectors are normally needed to do it. After assembly the joints can look perfectly acceptable, and then the cable…

MOSFET Soldering and Temperature Rise on a 3D Printer Board A 3D printer control board drives a heater, fans, motors and other outputs, so it carries several power transistors, driver devices, terminals and power components. If a load test shows that the device on one channel runs noticeably hotter than…

PCB Mixed Alloy Assembly: From Prototype to Volume Production 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 mixed alloy assembly gives you a practical advantage…

PCB Low Temperature Solder Assembly: Key Process and Quality Checks 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 low temperature solder assembly from the perspective of a…

Selective Conformal Coating for Industrial Display Boards An industrial display board carries a display interface, keys, a buzzer, communication terminals, the main controller and the power circuit, and a customer may ask for a coating so that the board survives the environment it will be installed in. The request is…

PCB Solder Alloy Selection: Practical Process Controls 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 solder alloy selection from the perspective of a PCBA factory floor, covering…
