Hot Air Rework: 6 Nozzle and Preheat Rules Hot air rework is the standard way to remove and replace a surface mount part after the board has been built, and it is also the easiest way to damage the parts beside it. The tool heats a small area with forced…

PCB Cycle Time Review: A Second Look 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 cycle time review from the perspective of a PCBA factory floor, covering…

PCB Cycle Time Plan: Laying It Out First 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…

Solder Mask Curing: Key Checks Before Release Solder mask curing is the sequence of tack dry, UV exposure and thermal bake that turns a printed liquid film into a hard, chemically resistant coating. Shorten a stage and the mask can pass a visual check while still being soft and under-reacted,…

PCB Cycle Time Data: What the Numbers Say 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…

Plating Throw: Key Checks Before Release Plating throw is the ratio of copper thickness at the centre of a hole to the thickness deposited on the surface of the same panel. A bath with good throw builds a hole wall that is nearly as thick as the surface copper, while…

Bad Mark: Key Checks Before Release A bad mark is a signal that tells the placement machine a unit inside the panel has already failed and must be left empty. The mark is applied after the electrical test or the inspection step that found the fault, and it travels with…

PCB Cycle Time Limits: Where the Edges Are 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…

Pattern Plating on PCB: 7 Controls That Fix Copper Thickness Pattern plating is the electrolytic step that builds copper on the traces and inside the drilled holes after the plating resist has defined which areas will be plated. It follows the electroless copper that makes the hole walls conductive, and…

Solder Mask Curing: 6 Stages From UV Tack to Final Bake Solder mask curing is the sequence of tack dry, UV exposure and thermal bake that turns a printed liquid film into a hard, chemically resistant coating. Shorten a stage and the mask can pass a visual check while still…
