PCB Coating Pinhole Detection: The Hole You Cannot See 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 coating pinhole detection from the perspective of a PCBA factory…

Schematic Conversion Between Design Tools: What Breaks Designs change hands. A product line is acquired, a customer supplies an older board for a derivative, an engineering team consolidates onto one tool, or a design is taken over from an external developer who used something else. In each case a schematic…

PCB Coating Coverage Inspection: Finding the Gaps in the Film 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 coating coverage inspection from the perspective of a PCBA…

Repeated Module Placement in Multi-Channel PCB Layout Many boards are the same circuit repeated. An eight channel amplifier, a four port transceiver, an LED driver array or a bank of identical sensor front ends: the schematic describes one channel and the layout has to place and route it several times.…

PCB Corrosion Test for Coatings: Checking the Protection 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 explains…

EMC Design Rules for High-Speed PCB Layout EMC problems are almost never solved by a component added at the end of a project. They are avoided by decisions taken at the start of the layout, when the placement, the stack-up and the routing of the critical nets are still open.…

PCB HAST Test Conditions: Damp Heat in a Hurry 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 HAST test conditions from the perspective of a PCBA factory…

Handling Power and Ground in a Mixed-Signal PCB Layout Mixed-signal boards are difficult for reasons that have little to do with the components. The resistors, converters and processors are all ordinary parts; what makes the design hard is that the digital section injects current into the same structures the analog…

PCB Humidity Chamber Testing: Living in Damp Air 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 humidity chamber testing from the perspective of a PCBA factory floor,…

PCB Thermal Cycling Chamber Setup: Heating and Cooling the Board 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 thermal cycling chamber setup from the perspective of a…
