PCB redesign. djt-e has done all optimizations and modifications djt-e could until the present moment. The current prototype (last picture) needs more hardware and firmware tests, maybe some further modifications in the project of the PCB, then can produce a batch of 100pcs for extensive tests and pre-compliance/EMC tests. If this project reaches expectations and goals, for me it will be like a small dream come true. Sirros IoT SX project. PCB: 10cm x 9cm, 1.6mm thickness, 8 layers PCB Stack: L1: Top L2: GND plane L3: Power plane L4: Signals L5: GND plane L6: Signals L7: GND plane L8: Bottom Blind vias: (vias that begin in an external layer and end on an inner layer) - L1 to L2 - L1 to L4 - L8 to L4 The light green circles surround signal vias that when they make the transition of the routing layer they change the ground reference plane. For all signal vias in which occurs this, there is a GND stitching via very close, to shorten the path of the return currents of the signal...

PCB design process In electronic design and development, attention should be paid to PCB design and electronic component selection. 1. PCB design shall consider wiring, SMT difficulty, separation of analog circuit and digital circuit, electromagnetic interference between components and circuits and other related issues. Pay special attention to the problem of interference, because such problems are sometimes hidden problems, which may appear at some time. It would be embarrassing if it appeared after large-scale production. 2. For the problem of component selection, the use of side door should be avoided in the selection of electronic components, because this component may face shutdown at any time or be difficult to be compatible with other components. Sometimes replacing a component will cause great trouble because the pin pin pin or drive is incompatible. For products, the use of mature and stable components can not only improve the stability of products, but also sometimes reduce ...

Our primary business is contract manufacturing for PCBAs in southern China, and although we do have customers throughout the world, but do not currently stock materials or finished product anywhere but China. Lead times vary, and really have to do with the complexity of the product and the components used. As I'm sure you know, components are the driver for lead-times on finished product in the current post pandemic world. If you do have customers that would need PCBA production services while taking advantage of the lower cost capability of China manufacturing, we would certainly be interested in the opportunity to quote the project. In addition, we can help with design services for new concepts, reverse engineering, product redesigns, etc. These engineering services are provided both locally in the USA and in China. We can also offer mechanical design as well, if there is a need for your customer.
How to Route Signals Before you start routing, let’s look at the typical PCB stackup you would use in a 6-layer PCB: In this stackup, the top and bottom layers are on thin dielectrics, so these layers should be used for impedance controlled signals. 10 mil is probably the thickest dielectric you should use because this will require microstrip routing with 15-20 mil width, depending on dielectric constant. If you’re routing a digital interface with differential pairs, the spacing will also allow a reduced trace width, which will allow you to route into finer pitch components. Just as an example, we have used a version of the above stackup for many of our small form factor networking products that support multiple multi-gigabit Ethernet channels. If you need to use much smaller trace widths on the outer layers, just decrease the outer dielectric thicknesses (maybe as low as 4-5 mil), and then add some thickness to the L3-L4 dielectric so that you hit your board thicknes...

.png "How to test the PCBA board?")
How to test the PCBA board? 1. PCBA board manual test Manual testing is to test directly by the vision and confirm the component mounting on PCB through vision and comparison. This technology is widely used. However, the large number and small components make this method more and more unsuitable. Moreover, some functional defects are not easy to be found, and the data is not easy to collect. In this way, more professional testing methods are needed. 2. PCBA board automatic optical inspection (AOI) Automatic optical testing, also known as automatic visual testing, is carried out by a special tester. It is used before and after reflow and has a good effect on the polarity inspection of components. Easy-to-follow diagnosis is a common method, but this method is poor in short circuit identification. 3. PCBA board flying needle tester Needle testing has been widely welcomed in the past few years due to advances in mechanical accuracy, speed, and reliability. In addition, the requirements f...

Why outsourcing electronic components procurement?With the refinement of industrial division of labor, more and more electronic product R & D companies streamline organizational structure, allocate limited resources in the two core competitiveness of R & D and sales, so as to outsource the cumbersome production and manufacturing links. In this trend, it is bound to increase the demand for PCBA labor and materials. Customers only need to provide design documents for electronic manufacturers to purchase electronic components and complete the PCBA manufacturing process according to the design requirements. This mode of labor and material contracting can save the staff cost and dull cost of customers' self built materials purchasing, inspection and warehousing. On the whole, it will save the total cost of customers' enterprises and improve the financial and product turnover efficiency. How can we ensure that the electronic components procurement is a genuine channel?We have a perfect ...

PCBA test (English PCBA test) refers to the electrical conductivity of PCBA circuit board mounted with electronic components and the test based on input and output values. In the design of PCB circuit board, there is a numerical relationship between different test points, such as voltage and current. It needs to use professional test equipment or manual operation multimeter to test the test points, so as to verify whether the actual PCBA Board meets the design requirements. PCBA test is the key step to ensure the quality of production and delivery. According to the test points, procedures and test steps designed by customers, FCT test fixture is made, and then PCBA board is placed on FCT test rack to complete the test< br /> PCBA testing principleConnect the test points on PCBA board through FCT test rack to form a complete channel, connect the computer and the burner, and upload the MCU program.
