China OEM pcba Manufacturer methods and tips

Both the OEM PCBA clone and the tear IC are part of reverse engineering. They don’t seem to be very related, but in fact the PCB is the supplier and the supplier of the electrical connection for chips. On the other hand, the chip is the key component of electronic products that perform computer and storage functions. Without an IC, the circuit board has no real value. In the area of ​​reverse engineering, the connection between the PCBA clone and the crack IC is so close that they are like twins.

The PCBA clone is a kind of reverse research technology that technicians use to analyze an advanced electronic product to obtain circuit boards for circuit board design, circuit diagrams, parts lists, technical files, etc. Digest applies this key information to the research and development of new products.

IC Crack is a kind of emerging reverse engineering. With the help of special devices, the MCU attacker can extract the main program from the chip using various technical methods, since the MCU design has some defects and shortcomings. Ultimately, Crack IC is used to examine the structural principle, the production process and the chip programs.

The two technologies also have some differences. The PCBA clone contains IC slots and other elements such as PCB design, parts list and schematic construction, but chip decryption is just an examination of the chip. Your success factors are also not the same. In general, the success of a PCBA copy depends on the strength of the technology, while a complicated IC crack takes longer because the attacker has to spend time finding gaps and bugs in the chip design. Chip decryption innovations can only be achieved through program decomposition or reverse IC design, which improves the internal performance of the electronic product. In PCBA copying, not only can the internal function be improved by a schematic modification, but the appearance of the product can also be changed by prototyping.

Looking

When looking for high-end software for circuit board designs, there are many things to keep in mind so that the product you receive is equipped with the necessary facilities at a reasonable price. However, if the product is good, it doesn’t hurt to pay a little more money.

Before purchasing PCB design software, you should review your needs. The software should offer features such as a user-friendly interface, manual routing, or tools for auto-rooting and auto-insert. The software should be able to create new parts and footprints, a standard library in which designs, multi-level hierarchies with schematic recording can be shared, and the spice scheme, network, or printed circuit board exported. Most important is an easy-to-understand tutorial that simplifies the manufacture of printed circuit boards.

There are a variety of software on the market that cover most of the above features and functions, such as:

EASY TO USE THE INTERFACE: This feature supports schematic and multispeed software and allows the creation of schemas in a very simple and fast process that can be easily managed by selecting, placing and connecting components in your documents and connecting them with wire and bus tools. . There is a tutorial that will guide you through each step of PCB design.

AUTOMATIC RUTING CONFIGURATION – This feature allows the routing of complicated circuit diagrams of SMD components and single-layer boards. There is software with two different routers, a shape-based router and a network-baseds router, which can be used to produce single-layer cards with bridge wires. This software supports tracking and processing of curved tracks in all sizes.

ADVANCED TEST SYSTEM – With this function you can test the circuit diagrams and modules of the circuit board and thus control the quality of the project at each stage. Features such as DRC and ERC allow you to check the distance between design objects and check for errors in schematic pin connections. The configuration includes the display of these errors in a graphical format so that error correction can also be performed without errors at every step. Functions such as Net Connective test the printed circuit board or electrical connectivity.

SHARE SETUP: This feature allows you to exchange schemas, schemas, and libraries with other EDA and CAD packages.

Also

Many companies first meet a new manufacturer of contract electronics by starting a questionnaire and then judging by their answers. Is that enough? Do the responses from different EMCs look the same or very similar?

Since this is not about reading the answers to the questionnaire, I am sure that you are the professional who reads your own supplier questionnaire. But how can you know more?

If you have the opportunity to visit them, go. Sometimes it can be a big surprise when you actually see the manufacturer. Not to mention whether the contractor’s workshop is well equipped or not or whether the management is well dressed. These are the details you should examine. Is your line set up for customer visits? Or focus more on practical application through efficiency and quality control? Decorate your factory very well. If so, why should you spend your time and money in a well decorated workshop? Everyone knows in many ways how to judge management based on conversations. But how should the management of an e-manufacturing service provider dress? Do you focus more on how you look than on how you do business?

If you haven’t had a chance to visit the contract manufacturer yet, read the emails. Many questions? If so, this is a good sign because it means they take care of you and take you seriously. Too many questions about product details? Why is the tolerance of a label size important to you? Why are you asking me to put up a simple resistance? Why would you like to know how to test the product at the PCBA level? Why do you want us to confirm a quality standard? Why did you tell me how to do cosmetic exams? Why do you have so many questions, can’t you decide for yourself?

Conclusion

When we watch sports, we see how the action takes place, how the scores go up and down and at the end of the day, at least when it comes to sports … there are winners and losers.

For suppliers and OEMs who are trying to continue working as a team … It doesn’t have to be that way!

End users need OEMs (Original Equipment Manufacturers) to offer cheaper, yet high quality products. First, there is nothing new here … Suppliers have to offer reduced part costs or these parts have to be manufactured more efficiently so that they only cost less or both.

Even if these points are true, another area of ​​consideration could offer additional cost savings. It is the added rhetoric with no added value that wastes time and increases costs for both suppliers and OEMs. This is the almost endless illusion of how the parts are made, what standards and set-up times should be used, and how other manufacturing details can be determined. Funny here … finally an agreement is reached between the supplier and the OEM.

Some critical questions:

Has this information been agreed for the next partial estimate and negotiation session?

Will the supplier and the OEM reinvent the rhetorical wheel? “”

When determining the drilling time, for example, it should be taken into account how often a hole with a diameter of ¼ “must be drilled through a plate made of ¼” stainless steel 304) with a Mazak Nexus 410 (with cut) high speed) only takes 7 seconds (tool )?

OEMs first try to identify vendors that offer lower prices, but try to find vendors that keep prices consistently low, especially when the OEM requests a change in functionality. Often the price can go up dramatically and appear to be unjustified. Since the OEM has already selected the supplier, the rhetoric continues, in which both the supplier and the OEM cause unnecessary costs.

What can a supplier do to reduce these costs?

Vendors can invest in cost estimation software and more technologically advanced jobs. The software can store this agreed information centrally and reduce rhetoric by using a consistent reporting tool during the negotiations. Result: OEMs get answers to make quick purchase decisions. Suppliers can quote more and focus on making more parts.

What can OEMs do to reduce these costs?

Electronics manufacturers can help their suppliers invest in software for cost estimation and better technological work. Provide information and performance studies to find out how parts can be made at a lower price. Result: In addition to the software advantages listed above, all manufacturing providers with better machining or manufacturing orders can, for example, manufacture better, faster and cheaper parts.

It is a simple team-based manufacturing approach.

US suppliers are an important part of our pcb manufacturing economy and the manufacture of high quality parts for consumers. OEMs and consumers need lower prices from US manufacturers to continue shopping. Thanks to the cooperation between suppliers and OEMs, our country can avoid foreign competition. If more OEMs use these software tools and are more receptive to offering these resources to their suppliers, negotiations with entire suppliers could be smoother, cheaper and with the ultimate goal that everyone can get a situation.
