PCB AOI Lighting Selection: Light That Shows the Fault 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 AOI lighting selection from the perspective of a PCBA factory…

Insulated Metal Substrate PCB: A Design and Cost Guide What an IMS PCB Is An insulated metal substrate board is a three layer construction: a metal base, a thin thermally conductive dielectric, and a copper circuit layer on top. The metal base is usually aluminium and sometimes copper. The dielectric…

CEM-1 PCB: The Low-Cost Single-Sided Laminate What CEM-1 Is CEM-1, composite epoxy material grade one, is a laminate with a cellulose paper core impregnated with flame retardant epoxy resin and faced with copper foil on one side. It is the cheapest material that still behaves like a printed circuit substrate,…

Electric Heater PCB: Design, Materials and Cost What an Electric Heater PCB Does An electric heater is a simple load and a surprisingly demanding control problem. The board that drives it has to switch several hundred watts, sometimes several kilowatts, read a temperature sensor and hold the element within a…

Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB OSP coating process from the perspective of a PCBA factory floor,…

PCB Gold Plating Bath Control: Holding the Gold Window 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 gold plating bath control gives you a practical…

PCB Layer Stack: What Every Layer Does The Anatomy of a Board A printed circuit board is a sandwich of conductive layers separated by insulating ones. The conductor is copper foil, patterned into traces, planes and pads. The insulator is a resin reinforced with glass fibre, supplied either as a…

PCB Tin Plating Bath Control: Keeping the Tin Bright 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 tin plating bath control gives you a practical…
