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 [...]

The Basic Knowledge of PCB in PCB Assembly

In today's society,PCB is used widely in our all-sides life.As a necessary part, it plays an important role. Therefore, we have to have a good knowledge of PCB. Today I summarized PCB knowledge for you.  Definitions: For standard PCB, it is the combination of bare board and components on it. While for bare board PCB, it is called printed wiring board. We usually call it PWB. (1) Traces: The base material of PCB is comprised of dielectric, heat insulation, uneasy to bend materials. On its surface, we can see thin traces, its material is copper. Originally the copper covered the [...]

PCB & PCB assembly E-test fixture

The fixture or shelf used for testing is called a E-test fixture; the test racks we know here are for PCB and PCBA (PCB assembly) What raw materials do you need? Acrylic plates, locating posts, ejector pins, cards, leads, etc..In order to select according appropriate materials to produce the E-test fixture We need to choose it based on the actual situation, it can greatly reduce the cost, at the same time a general base night repeated use can greatly reduce the cost, and make the E-test fixture making standardization, convenient production, improve the quality of the E-test fixture. The selection [...]

PCB assembly Defect Coverage Using Automated Optical Inspection (AOI)

PCB assembly Defect Coverage Using Automated Optical Inspection (AOI) Automated Optical Inspection (AOI), which is an automated visual inspection of a Printed Circuit Board (PCB), provides 100% visible component and solder-joint inspection. This testing method has been in use in PCB manufacturing for almost two decades. It plays a critical role in ensuring that there are no random faults in the assembly. The technique, which uses lighting, cameras, and vision computers, is incorporated in the assembly process to guarantee the highest possible quality throughout each phase of a product’s life cycle. The method enables fast and accurate inspection and can [...]

BENEFITS OF CONFORMAL COATING FOR PCB& PCB Assembly

A conformal coating is defined as a thin layer of transparent plastic that "fits" the body of the PCB and component. By being breathable, it forms a protective layer that protects against particular environmental conditions, but also allows any moisture trapped in the board to escape. The conformal coating is a protective coating for printed circuit boards (PCBs). It protects PCB components from moisture, heat, cold, dust, smoke, weather changes and other environmental conditions that can affect PCB performance. The use of a conformal coating on the PCB reduces the need for repair or replacement of printed circuit boards, thereby reducing [...]

Five knowledge points of PCB Design technology–Hitech Circuits Co., Limited

1: Print line width selection: The minimum width of the printed line is related to the current flowing through the line: the line width is too small, the resistance of the printed line is large, and the voltage drop on the line is large, which affects the performance of the circuit. The width, the wiring density is not high, and the board area is increased. In addition to increasing the cost, it is not conducive to miniaturization. If the current load is calculated as 20A / mm 2 , when the thickness of the copper foil is 0.5MM (generally), the [...]
