Do you know what is a PCB or Printed Circuit Board?

PCB or Printed Circuit Board is the traditional name for the bare board of which we produce with the layout data and which will be used to mount the components on. A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have [...]

Inspection Method of PCB assembly Short Circuit

PCBA(Printed Circuit board Assembly) short circuit is a relatively common failure in PCB Assembly. once PCB assembly occured short circuit, which requires the professional electronic engineers to analyze the reason and deal with it to avoid irreparable losses.   Inspection Method of PCBA Short Circuit   If the board (PCB) will adopt manual soldering, developing a good habit is much vital. First, check the circuit board visually before soldering, and use a multimeter to check whether the key circuits (especially the power supply and ground) are short-circuited or not; Secondly, once soldered a chip to the board, using a multimeter to check whether the power supply and ground are short-circuited or not; In addition, do not throw the solder iron randomly when soldering. If you throw the solder onto the [...]

PCBA assembly Appearance Inspection Instructions

Printed circuit board assembly (PCB assembly, PCBA), often use abbreviations—— PCBA, is an important electronic parts, is the support of electronic components,the provider of the electronic circuit connection.Because it is produced by using electronic printing technology, it is called "printed" circuit board.Before appears in the printed circuit board, electronic components of interconnection between relied on wires connected directly and form a complete circuit. Now, the circuit bread board only to exist as an effective experiment tool,but the printed circuit board in the electronics industry has become the dominant position. But most people still don't know what is PCBA  appearance inspection [...]

Why Flex and Rigid-Flex PCB Tooling Costs Higher

There are many factors that influence flex and rigid-flex PCB, here are some of them. Tooling charges comes down to volume. For rigid-flex and/or flex prototypes and small volume runs, most are manufactured with laser cutting or some type of mechanical routing. This is used to create the surface mount features in the Coverlays, part outline, and if required, the outline of the stiffeners. Electrical testing on these lower volumes is typically done with a flying probe. In volume production of flex and rigid-flex circuits, you need to switch over to steel rule dies or male/female punch and die sets. These steel [...]

Heavy copper PCB for new engery vehicles

Heavy copper PCB for new engery vehicles Heavy Copper PCB Board does not have a set of definition per IPC. According to PCB industry, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board. Heavy copper board normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors and new engery vehicles, etc.
