PCB Air Freight Handling: Moving It Quickly 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 air freight handling gives you a practical advantage when you…

Motor Driver Circuit Design From Requirement to Board A motor drive is designed backwards from the mechanical requirement. The torque, the speed and the acceleration profile decide the current, and the current decides the topology, the devices and the copper on the board. Requirements Before Topology The first document is…

Tin Pest: Low Temperature Failure in Solder Joints Tin is one of the most useful metals in electronics and one of the least stable. Below a well-known threshold it slowly transforms from the familiar silvery metal into a grey, crumbly powder, and the joints it forms begin to disintegrate from…

PCB Silicone Coating: Coating for Hot Places 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 silicone coating from the perspective of a PCBA factory floor, covering applying…

PCB Baking Profile Selection: Time and Temperature 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 baking profile selection from the perspective of a PCBA factory floor, covering…

PCB Sea Freight Moisture: Weeks at Sea 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 sea freight moisture gives you a practical advantage when you…

PCB Depaneling: V-Score, Routing and Laser Depaneling separates the individual boards from the production panel. It looks like a simple mechanical step, but it is where a finished assembly can be damaged by stress that leaves no immediate sign and appears later as a cracked joint or a delaminated corner.…

PCB Shipping Container Design: The Box It Travels In 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 shipping container design from the perspective of a PCBA factory…

Press-Fit Connector Assembly: Compliant Pins and Hole Fit A press-fit connector is attached to a board by forcing a compliant pin into a plated hole. There is no solder, no reflow and no thermal excursion, which is why the technology is used on thick backplanes where soldering would be difficult…

PCB Nitrogen Packing: Keeping the Air Away 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 nitrogen packing gives you a practical advantage when you choose…
