When it comes to brands, we can throw you a lot of well-known brands. Life brand advertising can be seen everywhere. Brand has far exceeded the value of its own material values，it makes personal use of a brand has been upgraded to meet the psychological and spiritual values. Therefore, once a product brand success,the economic benefits it bring will be immeasurable. Thus, that  a company establish a brand is very important.

WDF give guests a good impression, firstly reflected in the brand name. WDF is Wonderful meaning, it is an English word that means wonderful. It Contains praise meaning and the feeling is very good. So the brand name already has been a success. Secondly, it is the quality of the product. The success of an enterprise is not only the surface of things, really you need to have something inside. That is the product. How it reflects the value of your product? Your products will give good feedback to customers, so that customers feel that the use of your product is assured. Therefore, product quality is the most important. When a customer using your product feel at ease then your road to success began. Customers will continue to give you the next order, and even introduce his colleagues to give you new orders. This is the only way you can sell a better product. Quality is a quantitative change to qualitative change process, when more and more people know about your product ，after that people will be more concerned about your brand. People in the procurement time, will regard you as a contrast to the object. This time, your brand will play its powerful features, to bring you more customers. Furtherly, brand promotion is the premise of the brand started. WDF wants to do big business, wants more foreign friends know our brand, then you need to make greater efforts in the promotion. At present our company through the exhibition, the Alibaba, Global Sources and corporate websites to do their own brand. The company has foreign language department and sales department of Russian, is a relatively large sales team. Therefore, this requires the joint efforts of all the staff: to continue to do the promotion on the platform, fight promotions, lead to more customer focus; salesman to enhance their professional level, to show your specialty to your the customer, quality departments to maintain close contact with the plant, and to make sure the quality and quantity completed on time. Through continuous accumulation, expanding our customer base and our product quality assurance. And then we can get better and better WDF fame. Last point is to do for the success of a brand is too important for a company. Because the brand effect will not only allow us to get more customers, which in turn allows the body in its employees have a proud sense, can stimulate the morale of everyone. Let us work together to bring   Wonderful  into every corner of the world and achieve everyone Millions dream.

PCB processes

Panelization is a procedure whereby a number of PCBs are grouped for manufacturing onto a larger board - the panel. Usually a panel consists of a single design but sometimes multiple designs are mixed on a single panel. There are two types of panels: assembly panels - often called arrays - and bare board manufacturing panels. The assembler often mount components on panels rather than single PCBs because this is efficient. The bare board manufactures always uses panels, not only for efficiency, but because of the requirements the plating process. Thus a manufacturing panel can consist of a grouping of individual PCBs or of arrays, depending on what must be delivered.

Chemical etching is usually done with ammonium persulfate or ferric chloride. For PTH (plated-through holes), additional steps of electroless deposition are done after the holes are drilled, then copper is electroplated to build up the thickness, the boards are screened, and plated with tin/lead. The tin/lead becomes the resist leaving the bare copper to be etched away.

The simplest method, used for small-scale production and often by hobbyists, is immersion etching, in which the board is submerged in etching solution such as ferric chloride. Compared with methods used for mass production, the etching time is long. Heat and agitation can be applied to the bath to speed the etching rate. In bubble etching, air is passed through the etchant bath to agitate the solution and speed up etching. Splash etching uses a motor-driven paddle to splash boards with etchant; the process has become commercially obsolete since it is not as fast as spray etching. In spray etching, the etchant solution is distributed over the boards by nozzles, and recirculated by pumps. Adjustment of the nozzle pattern, flow rate, temperature, and etchant composition gives predictable control of etching rates and high production rates.

As more copper is consumed from the boards, the etchant becomes saturated and less effective; different etchants have different capacities for copper, with some as high as 150 grams of copper per litre of solution. In commercial use, etchants can be regenerated to restore their activity, and the dissolved copper recovered and sold. Small-scale etching requires attention to disposal of used etchant, which is corrosive and toxic due to its metal content.

The etchant removes copper on all surfaces exposed by the resist. "Undercut" occurs when etchant attacks the thin edge of copper under the resist; this can reduce conductor widths and cause open-circuits. Careful control of etch time is required to prevent undercut. Where metallic plating is used as a resist, it can "overhang" which can cause short-circuits between adjacent traces when closely spaced. Overhang can be removed by wire-brushing the board after etching.
