Security Camera PCBA Design: Key Requirements for Night Vision and Outdoor Reliability
A security camera has to capture clear footage in bright daylight and again at 3 a.m., sometimes through heavy rain or freezing temperatures. Behind that performance is a printed circuit board assembly (PCBA) that manages imaging and power, along with night vi
Creepage and Clearance Requirements for Inverter PCBs
Printed circuit boards (PCBs) are shrinking in size with every passing year, but their complexity and power density are increasing. Today, even a millimeter of board space holds value. This requires that pads, traces, component leads, and vias be placed precis
Heavy Copper PCB Design for High-Current BMS Applications
A battery pack that delivers 100 A or more puts every millimeter of its management board under load. Each trace and via adds resistance, and that resistance turns into heat at a rate of current squared times ohms. Heavy copper PCB design keeps those losses low
BESS PCBA Manufacturing: Key Reliability Requirements
Battery energy storage systems (BESS) are expected to work for a long time. They can sit in a cabinet or container for years and cycle through charge and discharge every day.ย These systems depend on electronics that can withstand continuous operation. Much of
How to Select a PCB Assembly Supplier for Energy Storage Systems
Energy storage systems place unusual demands on electronics. These systems usually involve high-voltage and high-current long-duration operations.ย A PCB inside such an ESS may be responsible for cell monitoring, temperature sensing, balancing, protection, com
What Is Electronic Manufacturing Services (EMS)? A Complete Guide
Pick up almost any electronic device on your desk right now, and there’s a good chance the company whose logo is on it never actually built the thing. This is how the electronics industry works today.ย Behind most consumer brands is a network of manufact
