Q:What are the materials used for the Merrillas on PCB circuit boards?: Mylar sheet (MYLAR film) is a PET polyester film, it is by the dimethyl terephthalate and ethylene glycol in the relevant catalyst with the help of heating, after ester exchange and vacuum polycondensation, biaxial stretching film.

Q:What does the printed motherboard mean?: but Is not the same, so the assessment of the industry when the two can not say the same. For example: because there are integrated circuit parts loaded on the circuit board, so the news media called him IC board, but in essence he is not the same as the printed circuit board. We usually say that the printed circuit board refers to the bare board - that is, no components on the circuit board.

Q:Six-layer or four-layer PCB board What does this mean? Is the line inside the circuit board: Yes, the line can be inside the circuit board. You take the circuit board, look at the light to see it.

Q:PCB printed circuit board, the "printed" is not referring to thermal transfer? Mass production PCB is also produced by thermal transfer method?: Not the heat transfer, where the printing is an image of the argument, because the PCB line looks like the same as printed on the substrate.

Q:Multilayer circuit boards, is not all power must be placed on the inner layer: Double panel is the middle layer of media, both sides are the line layer. Multilayer board is a multi-layer wiring layer, between the two layers is the dielectric layer, the dielectric layer can be done very thin. The multilayer circuit board has at least three conductive layers, two of which are on the outer surface, and the remaining layer is integrated in the insulating plate. The electrical connection between them is usually achieved by plating through holes in the cross section of the circuit board.

Q:Pcb board on the big black dot chip package called what?: Printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic components of the electrical connection provider.

Q:Do PCB board board In addition to materials such as CCL, there are other materials of the board?: 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 product 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:PCB circuit board? What is it?: As electronic devices become more complex, more and more parts are needed, and the lines and parts on the PCB are becoming more and more dense. Bare boards (no parts on top) are also often referred to as "Printed Wiring Board (PWB)". The board itself is made of insulated and non-bendable material. On the surface you can see the small line material is copper foil,

Q:Circuit board display device which: Through Hole: There are metal vias and non-metallic vias, where metal vias are used to connect the components between the layers of the pins.

Q:Multi-layer circuit boards and single-layer circuit board how to distinguish: Comparison of the most common, the most simple way to distinguish, pick up the light, the inner core is opaque, that is, all are black, is the multi-layer board, and vice versa is a single double panel, and single
