All along, Jieduo state technology in the integrity of innovation, people-oriented business philosophy to customer demand-oriented, give full play to the advantages of talent, and continuously improve the professional electronic PCB assembly service capabilities.
The advantage of Jieduo state technologyelectronic PCB assemblyis that it can provide more professional and thoughtful solutions timely and accurately according to the actual needs of customers.At the same time, Our company follow the latest developments on Industry and agriculture,Electronic Component,PCB circuit board, and establish long and steady partnership relation with many well-known enterprises in the same industry , to provide customers with the most professional, advanced turnkey PCB assembly.Details:
PCB Assembly
Design in different stages need to set up different points in the layout phase can be used to carry out large grid layout of the device;
For IC, non-positioning connectors and other large devices, you can use 50 ~ 100mil lattice precision layout, and for resistive capacitors and inductors and other passive small devices, can be used 25mil grid points for the layout. The accuracy of the grid is conducive to the alignment of the device and the appearance of the beautiful.
PCB layout rules:
1, under normal circumstances, all components should be arranged on the same side of the circuit board, only the top components too dense, in order to some limited and small heat of the device, such as chip resistors, chip capacitors, paste Chip IC on the bottom.
2, in ensuring the electrical performance of the premise, the components should be placed on the grid and parallel to each other or arranged in order to be neat, beautiful, in general, does not allow the components overlap; components to be compact, the components in the entire layout should Uniform distribution, density consistent.
3, the different components on the circuit board adjacent to the minimum spacing between the drawings should be more than 1MM.
4, from the edge of the circuit board is generally not less than 2MM. The best shape of the circuit board is rectangular, aspect ratio of 3: 2 or 4: 3. circuit board ruler greater than 200MM by 150MM, should consider the circuit board can withstand Mechanical strength.
Layout skills
In the PCB layout design to analyze the circuit board unit, according to the function of the layout design, the circuit of all components layout, to meet the following principles:
1, according to the circuit of the process of arranging the location of the various functional circuit unit, so that the layout of the signal flow, and make the signal as much as possible to maintain the same direction.
2, to each functional unit of the core components as the center, around him to the layout. Components should be uniform, overall, compact arrangement on the PCB, to minimize and shorten the lead between the components and connections.
3, in the high frequency of the circuit, to consider the distribution of components between the parameters. General circuit should be arranged as far as possible in parallel components, so not only beautiful, but easy to install and easy to mass production.
