Q:PCB plate manufacturers are famous what
Sunrise, Matsushita, Arlon, Nelco, Rogers, Tanconic, polyflon, etc.
Q:What is FR4 sheet
FR-4 is a glass fiber epoxy resin CCL, a circuit board in the substrate, in fact, you should have seen, such as the kind of small game machine to open, inside the green board is FR-4 to do circuit board. FR4FR5 epoxy board by a special electronic cloth impregnated with epoxy phenolic resin and other materials by high temperature and high pressure hot plate made of laminated products. With high mechanical properties and dielectric properties, good insulation properties and heat resistance and moisture resistance, and a good mechanical processing. Application: for electrical and electrical equipment for the insulation structure of parts, also widely used In the PCB test; and can be used in humid environmental conditions and transformer oil.
Q:The most commonly used gas shielded welding consumables are certainly different from the material being welded.
1, in most cases, sheet material and welding material is certainly not the same, the two are not comparable. 2, the plate is usually made of standard size flat rectangular building material board, for walls, ceilings or floor components. Also refers to the forging, rolling or casting made of metal plate. Divided into thin plate, medium plate, thick plate, special thick plate, usually made of standard size flat rectangular building material board. 3, the wire is used as a filler metal or as a conductive wire welding material. In the gas welding and tungsten gas protection arc welding, the wire used as a filler metal; in submerged arc welding, electroslag welding and other melting gas protection arc welding, the welding wire is both filled with metal, but also conductive electrodes. The surface of the wire is not coated with an oxidative flux.
Q:What are the types of boards on board?
94V0: Flame-retardant cardboard (die punch) 22F: Single-sided half-glass plate (die-punching) Fr-1 CEM-1 (mold punching) CEM-3: double-sided half-glass plate (in addition to double-sided cardboard outside the double-sided low-end material, a simple double-sided board can use this material (single-sided glass fiberboard (must be computer drilling, can not die) , Than the FR-4 will be cheaper 5 to 10 yuan / square meter) ...
Q:How to change the cabinet board is not Jilin forest workers dew river plate
The easiest way is to see his authorization certificate, or go to the official website of Jilin forest workers to see the brand has not bought it in the plate, there is the general Jilin forest workers are the subject of the plate, you can directly see the sheet Logo.
Q:PCB sheet problem
Only from the picture, it is difficult to judge, such as the picture should be a single panel, the first white substrate may be rogers some models may also be cem-1. The third type may be glass fiber cloth fr-4. In fact, the use of plate to see the nature of the circuit and the use of the environment. For example, there is no special circuit can be used fr-1.fr-4.cem-1 can be. High circuit frequency can be used Rogers series plate, more than 5g frequency should be used ptfe microwave plate.
Q:What are the CTP plates?
Photopolymerized media This type of plate is usually made of aluminum, photosensitive layer and surface layer. The photopolymerizable layer is mainly composed of a polymerized monomer (+ oligomer), an initiator, a spectral sensitizer and a film-forming resin. The initiator is widely used as a multi-initiator system with high quantum efficiency. The effect of the spectral sensitizer is to effectively extend the range of the initiator to the luminescence wavelength region of the laser. It can now extend to 488nm (ion laser) and 532nm ( Multiplied YAG laser). The role of the surface layer is mainly the atmosphere of oxygen molecules separated, to avoid its into the photosensitive layer, in order to improve the photosensitive layer of the chain growth efficiency, resulting in high sensitivity. As a result of these effective measures, the photopolymerization of the direct plate of the sensitivity has been greatly improved, the minimum imaging exposure has dropped to about 10μJ / cm2, second only to the silver salt type of direct plate, and this plate structure Simple, resolution, printing rate and post-processing and conventional PS version similar or even better. Since the range of intrinsic photoreactivity of most efficient initiator systems is in the ultraviolet region and the photometric range extends to the range of the emission wavelength of the UV-LD laser, the photopolymerized direct plate will become the next generation of UV direct Preferred system, has a very good development prospects.
Q:What does the plate open?
Sheet material is based on their own use of the drawings size, the large plate into a process to meet their own size.
Q:What is the difference between the addition of the plate and the Eo grade plate?
1.E0 grade plate refers to the formaldehyde emission is less than or equal to 0.5mg / l of the plate products 2. No aldehyde addition refers to the absence of formaldehyde material added plate products, meaning no formaldehyde 3. To know the world does not absolutely contain formaldehyde products, even if there is no formaldehyde added to the wood comes with formaldehyde, but the content is very low harmless to the human body, like apples, beer, trees and so naturally contain their own formaldehyde
Q:What is MDF?
1, MDF is a medium density fiberboard (English name: Medium Density Fiberboard, abbreviated as MDF, referred to as MDF). 2, medium density fiberboard is a wood fiber or other plant fiber as raw material, broken, fiber separation, drying urea urea resin or other suitable adhesive, and then made by hot pressing a man-made sheet. Its density is generally in the range of 500-880 kg / cubic meter, the thickness is generally 5-30 mm. 3, medium density fiberboard is the mid-sixties developed products, in recent years the rapid development of production. Because it has excellent physical and mechanical properties, decorative properties and processing performance.
