1. The product always has a variety of small problems, how to keep changing?

In the process of product development, we will certainly encounter various problems. The key is to solve these problems in the process of development or after the product is launched? If it is solved after going public, the cost will be very high, tens or even hundreds of times higher than that in the research and development stage, and it will also bring bad customer impact. To avoid this problem, we need to find an experienced and powerful manufacturer to cooperate, especially in the development of electronic products. It takes at least 10 years to make a qualified product. Tongwei technology has nearly 20 years of experience in electronic products industry, and has its own product reliability laboratory, which can solve 90% of the problems in the R & D stage. Don’t worry even if there are problems after going on the market. Tongwei technology will be self driven, constantly find and improve the feedback problems in the manufacturing process and customers after going on the market, constantly improve customers’ products, help customers seize the market, and help themselves.
2. What should outsourcing companies do when they sell our designed products to the outside world and seize our business?
This kind of thing has happened a lot in the south. It’s a headache and the customers have no idea. Our views on such things: 1. What is your business model? For example, what Tongwei technology does is to provide customers with one-stop service for product development, production and manufacturing, which does not involve product sales. It focuses on its own field and constantly enhances its technical ability in all aspects, so as to continuously provide customers with better product services. If you step into a field you don’t know because of temptation, you will lose your direction, your business model and original intention, and it’s hard to last long. 2. I believe in the theory of causal cycle in Buddhism. If you lose your character because of small profits and lose one customer as a customer, you can’t imagine it in the long run. On the contrary, if every customer has a good service and left a good reputation, the customer will introduce other customers, so that they will not worry about no business. Fortunately, the customer satisfaction of Tongwei technology is very high. Word of mouth has accumulated a lot of reputation and customers. Most of the customers have embedded the R & D department and production department into the customer company management system, realizing the common growth of Tongwei technology and customers.
3. What should we do if the original outsourcing team no longer provides technical support for the products that were originally developed by outsourcing and the products have problems after going on the market?
We have encountered a lot of problems in our previous projects. This is determined by the business form of outsourcing development: outsourcing development is bound to need a phased end point, but the product just needs a long-term iterative process, which is an irreconcilable contradiction. For the outsourcer, if long-term support is formed after the price of the contract is determined, the cost will be huge, so they will not be willing to provide long-term support for the product, and the customer’s product must need continuous technical support after mass production, so the conflict between them is inevitable. In order to avoid this problem, Tongwei technology proposes a one-stop service of product R & D, production and manufacturing. As long as customers choose us as partners, we will continue to support until the end of the product life cycle!
4. What should we do if the service attitude of the outsourcing company is very poor?
Outsourcing service companies are mostly founded by technical personnel. The working characteristics of technical work determine that technical personnel love to dig corners and are sensitive. These characteristics will be brought into the operation of the company. For example, outsourcing service companies often design according to their imaginary customer needs rather than their real needs, which leads to various misunderstandings in the process of communication with customers and brings inconvenience to both parties. Tongwei technology was initially established as a service-oriented technology company. It is the first priority to provide customers with services beyond their needs. Put this position, and the relationship between customers is very harmonious, also won the trust of customers.If you have any questions or quotation about PCB design, please email us.
