Q: What kind of plates are used for building models? In addition to the abs board kt board: With snowflakes

Q: What are the advantages of Yixing sheet compared to other plates?: Compared with other, Yixu sheet first is a big brand is guaranteed, and is committed to doing high-end health and environmental protection of the plate, and good quality is not too expensive, cost-effective.

Q: Do pcb circuit board which several kinds of plate: Divided into two categories: rigid substrate materials and flexible substrate materials. Ordinary rigid substrate material is an important varieties of CCL. Copper brass board classification of a variety of ways. Generally, the reinforcing material of the plate is divided into five categories: paper base, glass fiber cloth base, composite base (CEM series), laminated multilayer plate base and extraordinary material base (ceramic, metal core base). If the board is adopted by the resin adhesive different classification, the common paper-based CCI. There are various types such as phenolic resin (XPc, XxxPC, FR-1, FR-2, etc.), epoxy resin (FE-3), polyester resin and the like. Common glass fiber cloth CCL has epoxy resin (FR-4, FR-5), which is the most widely used glass fiber cloth type. In addition, there are other extraordinary resin (glass fiber cloth, polyamide fiber, non-woven fabrics to increase the material): bismaleimide modified triazine resin (BT), polyimide resin (PI) , Diphenylene ether resin (PPO), maleic anhydride imide-styrene resin (MS), polycyclic ester resin, polyolefin resin, and the like. According to CCL flame retardant performance classification, can be divided into flame retardant (UL94 a VO, UL94 a V1 level) and non-flame retardant (UL94 a HB class) two types of boards. Nearly two years, with the environmental issues more attention, in the flame retardant CCL and separate a new non-brominated species of CCL species, can be called "green flame retardant cCL". With the rapid development of electronic products technology, the cCL has a higher performance requirements. Therefore, the performance classification from the CCL is divided into general performance CCL, low dielectric constant CCL, high heat resistance CCL (general plate L above 150 ℃), low thermal expansion coefficient CCL (generally used for packaging substrate ) And other types.

Q: What about the quality of the new millennium?: This time you count the people, and my house when the house I studied the whole plate over time, the new millennium plate in general is a large manufacturers of products, in the high-end look, there is also a king coconut brand (first-line brand ), The new millennium is an economic series, the price is much cheaper than the bunny Moganshan millennium boat, the quality of these brands is almost the same, even better, because after all, the product is their own manufacturers, unlike those big brands, some products Not their own production, to go to the small factory to find almost OEM, environmental protection can not guarantee ,,, the new millennium home with a very appropriate, and now have E0 and E1 level, environmental protection coefficient is fully standard, miscellaneous brands and small factories of the most Do not use, even if the quality can be, but the environmental protection factor is certainly not up to the standard.

Q: Always said that the plate is very complex, think about learning a little professional knowledge: Can be distinguished by the following steps and methods: First is "see", but also to see the focus. Good plate surface smooth and smooth, the edge of the board is very clear. As well as the packaging on the plate is clear, the above name, address, grade, specifications and other information are complete, not clear, incomplete information or more attention to the plate, and may be added to the color of the plate. Two smell, because the legendary formaldehyde is released from the plate, will directly affect people's health. Good plate not only good choice of materials, but also for the adhesive glue is environmentally friendly, even if the number of more stacked together, it will not emit a very pungent taste. If the choice of a plate placed in the home there is a very obvious pungent chemical smell, it should be noted. ?Three saws, before the purchase can be a small sample to the business, and then cut it to see its inner core, a good plate section level is very clear, because it is a layer of paste a very tight, very good convergence, and those miscellaneous Wood stitching the poor quality of the plate core is not dense, must not buy. Four test, through the relevant identification agencies, with professional tools and related technical means to identify the plate to determine the quality of good or bad, this method is more professional and accurate. Plate material is also an important factor is the moisture content, the general moisture content of the plate should be less than 16%, if too high that is not good, may be a while will be mildew or deformation.

Q: What is the material in the timber? What is the plate?: The specifications of the material is the buyer's request to the wood processing into the required specifications such as 2 cm long 2 cm wide and 1 meter long and other special specifications, the buyer bought a little bit in the processing can be used, the plate is we often see the mountain wood processing Into a piece of one

Q: See a lot of people with black frame, comfortable?: The most common: metal, sheet, pure titanium, solid wood, TR90 Now the glasses frame whether the brand or frame color or the production of materials are varied. A pair of beautiful glasses is not only beautiful appearance, but also need to know when the wearer face and glasses with how to match, so that the more perfect, glasses will play its role in the modification, so you more attractive. Here to understand what glasses look good. Black box glasses. Black-rimmed glasses to wear after the arts Van special thick, and personal temperament will be changed, so that the current market is particularly popular. Black-rimmed glasses to wear, the more prominent personal contours and the overall personal characteristics, therefore, wearing black-rimmed glasses, then in addition to the appropriate face and color, wearing dress and eye makeup are very important, such as Zhao Wei wearing black box glasses , Highlighting the side with a round black frame brought by the charm, simple atmosphere, and its own unique atmosphere is very strong. Today's sheet glasses can be described as all kinds of people are particularly fond of the work complex and delicate, diverse styles, it is important that the color is good, not allergic, it is not easy to fade, it can be wild, itself is in the high-end frame. Whether it is from their own grades or style design is very advantages, and many brands of glasses are made of sheet metal, such as by the industry more appreciated Levi's frame, is used to produce high-grade sheet, beautiful appearance, Wearing fashion is also very good. What glasses are good-looking? Each pair of glasses have their own characteristics, have their own bright spots, a reasonable choice, the correct match, after wearing are generally very good. Moreover, the spectacle frame itself is an ornament, plays the role of landscaping. Domestic brands can consider the trend of the brand "wood ninety", a physical store.

Q: South Asia, Health benefits, Teng Hui FR4, which is relatively expensive?: South Asia and the benefits of the best technology, but South Asia has its own upstream industry support lower cost, cheaper, raw technology and quality control better.

Q: TR90 material, in the glasses frame classification inside the plate or injection molding rack: Calculated sheet, the injection of relatively hard, easy to break.
