Composition of PCB manufacturing production cost: The production cost of PCB products refers to the total of direct materials, direct labor, direct labor and other direct or indirect costs actually consumed in the production process
This paper introduces the inspection requirements of PCBA processed products: 1. Inspection requirements of PCBA processed products; 2. Quality requirements of component mounting process; 3
Shenzhen kingford is a PCBA processing manufacturer with more than 20 years of experience in PCBA processing. We have our own SMT processing plant, which can undertake mass SMT SMT processing services. Next, we will introduce what problems need to be cons
What is printed circuit board DFM: Product Manufacturability Design for short DFM. It is a discipline that studies some design behavior rules of the relationship between the physical design of the product itself and the parts of the manufacturing system,
Core and key points of SMT process: The goal of SMT process is to produce qualified solder joints. A good solder joint depends on the right pad design, the right amount of solder paste and the right reflow temperature curve
PCB hard board and FPC soft board difference: 1. Rigid PCB: often used as motherboard, cannot bend, 2. Flexible board: FPC also known as flexible circuit board, can be bent
The reasons for the appearance of virtual welding in PCBA processing are as follows: 1. Oxidation of pad and component pins; 2. Less tin; 3. The temperature is too high or too low, 4 welding paste melting point is low, 5, solder paste quality problems
When designing and wiring PCB, it is required to do as much as possible:1. If the wiring space permits, insert a ground wire or ground plane between the two lines with serious crosstalk, which can isolate and reduce crosstalk. 2. When electromagnetic fiel
5 suggestions to solve the problem of component shortage: 1. Expand the breadth and depth of cooperation between component suppliers; 2. Order to be prepared in advance, 3. Manage priority, 4. Reduce component loss, 5. Respect suppliers
The performance of PCB board is determined by the material used (high Q value), wiring design and several layers of board. The quality of PCB board has nothing to do with PCB color
PCBA batch processing success of the four secrets: one, planning in advance, two, looking for suppliers, three, evaluation of capacity and capacity, four, trust your suppliers
There are five common principles in PCB design: component arrangement rules, according to the signal direction layout principle, electromagnetic interference prevention principle, thermal interference suppression principle, adjustable component layout pri
