Q: What kind of PCB need to use Anti-CAF sheet: Anti-CAF is a material with special characteristics! In fact, the ordinary FR4 sheet also has enough of this feature, but in the special areas of the product may require more stringent reliability, so the material supplier was the introduction of such a special plate! Electronic migration is mainly a greater impact on the environment, such as humid environment will exacerbate the risk of electronic migration! From the product structure, such as the spacing between the holes is too small, will also cause greater risk!

Q: What is the difference between the addition of the plate and the Eo grade plate?: 100% of the addition of non-formaldehyde-free plate and E0-type plate is different from the use of glue is not the same, E0-class plate is urea-formaldehyde resin, 100 wins and no use of non-formaldehyde plate is the use of formaldehyde-free US fourth generation MDI glue.

Q: How to do the corn stalks: Process Technology Line: 1. Straw density plate: Air dry straw → impurity removal → cut off → wind selection (blown out of the heart) → cans → high pressure steam → spray → fine → spray → drying → pavement → preload → hot pressing → edge → cutting → packaging → finished product 2. Straw crushed plate (particleboard) Drying Straw → Cutting → Wind Selection → Recovering → Drying → Screening → (Surface Layer, Dust, Core Material) → Mixing → Pavement → Preloading → Hot Press → Edge → Cutting → Inspection → Packaging 3. Straw composite board Straw → Cutting → Steam Blasting → Mixing → Paving → Wood Veneer → Glue → Preloading, Hot Press → Side → Varnish → Sanding → Finished 4. New wall materials: Corn stover high grain straw → election → leaves → cut → pavement → irrigation → do the surface layer → veneer → sanding → finished In addition to the above processing, the straw can also be used for pulp making after steam blasting, which is about a third less expensive than traditional pulping methods and only one third of the traditional method. It is helpful to solve the problem of pulp gap caused by the forced cessation of small papermaking by the state. Fourth, the main technical key and expected to achieve the technical and economic indicators: 1. Main technical key: ① developed as low as possible, environmentally friendly, waterproof superior, infiltration of a good name of the glue. ② design and improvement of grading pavement. ③ steam blasting equipment selection and the determination of the main process parameters. ④ hot pressing and cold pressing process parameters adjustment. 2. Expected technical and economic indicators: ① adhesive; solid content: 60% -65% ??????????Free formaldehyde content: 0.2% or less ??????????Viscosity: coated with 4 cups: 30 ℃ 10-20 seconds (fiberboard) ?????????????????????????????????50-65 seconds (particle board)

Q: Many cabinet manufacturers will use their own plate labeled as "the whole board", the Internet can not find the whole plate in the end what is the essence. I would like to ask you, the whole board is what board?: The substrate is used outside the re-processing of a moisture-proof board, to achieve a better moisture-proof performance is also high temperature, in fact, this also depends on the home that is used in moisture-proof plate substrate. Now is the Jilin Forest workers Lushui River plate the best plate.

Q: How to color the plate after carving: First with the newspaper accounted for four weeks, leaving the word, you can spray later.

Q: What is the difference between wood and wood?: Wood can be called wood logs is the original length to the size, shape, quality standards or special provisions cut into a certain length of the wood section, the wood section called logs. Wood is processed semi-finished products. The use of wood: to be divided into direct use and chemical or special processing to do the use of raw materials. Wood direct use are: construction, pit wood, pillars, sleepers, packaging, furniture, craft sculpture, ships, sports equipment, cultural and educational supplies, musical instruments, decoration, grenade handle, butt, After chemical processing or special processing to do the use of raw materials are: paper, rayon, regenerated cellulose, nitrocellulose, cellulose acetate, ethyl cellulose, hydroxy cellulose, phenyl cellulose.

Q: PCB board material how to identify: PCB board material identification, can be carried out from the following four aspects: (1) dimensional stability In addition to pay attention to X, Y axis (fiber direction and horizontal direction), but also pay attention to the Z axis (plate thickness direction), due to thermal expansion and contraction and heating reduction factors easily lead to silver plastic conductor fracture. (2) electrical and water absorption FR-1 is better than FR-1 and XPC in terms of dimensional safety, electrical and water absorption, so that the insulation of the insulator in the absorbent state is reduced, so that the metal is moved under the potential difference. Production of silver through-hole printed circuit board, to use special FR-1 and XPC paper substrate. (3) ductility Copper plating through the copper hole is a continuous crystal, there is a very good ductility, not like silver, carbon ink in the thermal expansion and contraction, easy to interface separation and reduce the conductivity. (4) migration Silver and copper are metal materials, easy to oxidize and restore the phenomenon caused by rust and migration phenomenon, due to the difference in potential, silver than copper in the potential difference between the trend of prone to silver migration (Silver Migration). Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit.
