  • In determining the bare printed circuit board assembly cost, this involves the price, quality, and delivery time of the raw materials, which focuses on their type and thickness, PCB size, and layer count. ...

  • PCB stands for Printed circuit board, which is the chips that supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.PCBA stands for ...

  • EMPTY WELDING:When two solders are heated differently or one of them has oxidation layer and dirt on the surface, the molten tin will adhere to the solder pad of the solder with higher temperature and clean surface, but not to the solder with low temperature and dirty surface, so that there is stil...

  • The general production cost of PCB is 30~60% for direct and indirect raw materials, including substrate, film, copper foil, solder resistance, dry film, drill bit, heavy metal (copper, tin, lead) and chemical consumables. The consumption of these raw materials is directly related to the appropriate...

  • This should be examined in three parts:1. The LED lamp bead or resistance may be damaged.2. It may be component virtual welding or de-welding.3, may be what you said, the led pcb board is not good, can be used to detect the multimeter between the components of the line, whether disconnected.In orde...

  • 1. It is strictly prohibited to use the grounded test equipment to touch the live TV, audio, video and other equipment on the base plate to detect the PCB board without isolating transformerIt is forbidden to directly test TV, audio, video and other equipment without power isolating transformer wit...
