How to Design One-Sided Exposed Copper Through-Hole Pads: Design and Assembly Considerations In conventional PCB design, through-hole components are generally designed with solderable copper pads exposed on both sides of the circuit board. However, some applications require a through-hole pad to be soldered from only one side while the…

FPC Tear Prevention Line: Design Rules and Process Checks A flexible circuit bends, folds, and fits into tight mechanical spaces. That same thin structure makes it fragile during panel separation. When a connection bridge is weak, manual depanelization can tear the polyimide and damage nearby traces. An FPC tear prevention…

FPC to PCB Connection: 7 Common Methods Explained A flexible printed circuit bends, folds, and reaches into spaces a rigid board cannot enter. A rigid PCB holds components, spreads heat, and keeps dimensions stable. Joining the two is where many compact products succeed or fail. The method you choose fixes…

SMT Flying Probe Testing: Process, Capabilities and Benefits Flying probe testing checks an assembled board with moving probes instead of a dedicated fixture. The machine drives its probes to programmed coordinates and measures what it finds there. This makes the method practical for prototypes, low-volume runs and designs that change…

How to Panelize PCBs for SMT Assembly Production Panelization turns several small boards into one rigid unit that the SMT line can handle. The panel must survive paste printing, placement, reflow, inspection, and depanelization without losing alignment. Each of those steps puts its own demand on spacing, support, and reference…

PCB Panelization Guidelines: Edges, Tooling and Fiducials A panel is not just several boards joined together. It is the mechanical interface between your design and every machine that will touch it. Process edges carry the panel through conveyors and assembly equipment. Tooling holes fix its position. Fiducial marks let vision…

PCB Copper Pour Guide: Uses, Copper Weight and Design Copper pour fills the unused areas of a circuit board with solid copper. The added copper may connect to ground, a power net, or another assigned net. Designers use it to lower ground impedance, spread current, move heat, and steady return…

Stamp Hole Probe Design for PCB Test Fixtures A stamp hole probe is a spring-loaded contact that presses into a plated hole or test point on a PCB. It carries signals from the board to the test fixture and the measurement system. Engineers use these probes when they need repeatable…

Backplane PCB: Types, Materials, Design and Build A backplane PCB carries the interconnection load for an entire modular system. It links daughterboards, cards, and connectors through one structured platform for power, clocks, and high-speed data. The board rarely does the computing itself, yet every module depends on it. That dependence…

Semiconductor Test PCB: Types, Testing and Design A semiconductor test PCB connects a device under test to the tester that measures it. The board carries power, high-speed signals and mechanical alignment between the device and the automatic test equipment. Unlike a product board, its job is measurement accuracy rather than…
