Electronic Product Design Using Circuit Boards and Process Introduction

Sheet type
At present, FR-4 material can provide grade A plate and KB-6160A plate, aluminum plate 1060 aluminum.
Sheet type
Board layers
We can choose from 1,2,4,6,8 floors. This refers to the 1st floor is a single panel, the 2nd floor is a double-sided 4th floor is a 4th floor, and so on, the more floors, the higher the cost.
Board size
It refers to the length and width of the PCB. If it is the size of the circular plate, it is calculated according to the diameter. If it is an irregular PCB, the size refers to the largest profile. The size of the board is a tolerance range, the general shape of the range of +/-0.2mm or so. If you have other unconventional requirements on the PCB size, please be sure to note clearly, otherwise, according to the industry standard routine processing, in addition, in the design, the shape should be designed with the keep out layer as much as possible, and must pay attention to usage, not with the mechanical layer Mixed use, otherwise it is easy to make mistakes.
Number of boards
Refers to the number of pieces that need to be customized. In order to facilitate factory production, the quantity is generally rounded.
Number of puzzles
Refers to the PCB with different models in the same file. The same section of the PCB is not used to make money. How to distinguish between them requires the factory to raise the level of the overall examination.
Shipping method
Can be understood as the board to be received is monolithic or contiguous, this is also required to match the size of the order, contiguous shipments need to note the imposition method (with imposition of the best).
Half hole process
Half of the holes require copper and half no copper. To do this kind of board to go through a drilling process more than the normal board, drilling half of the copper.
Board thickness
Is the thickness of the PCB board, this way needs to specify the tolerance of the board thickness, the company is currently using the FR-4 military-grade A material, the tolerance is relatively small is generally controlled at about 10% of the board thickness. This 10% is mainly due to process control in production. If you have special requirements for PCB thickness, please be sure to clearly note, or otherwise routinely deal with according to industry standards. Thickness is also another driver of price fluctuations. Normal thickness is 0.6-1.6mm normal thickness. If it is not within this range, the price will be much higher. Please order when you order! (Thicknesses such as 0.4, 2.0, 2.5, and 3.0 are relatively high relative to prices of 0.8-1.6).
Solder resist color
Refers to the apparent color of the PCB, the company currently offers a variety of colors, specific reference to electronic product design process capabilities, the mainstream color of the mainstream is green.
Character color
Refers to the color of the apparent electrical silk screen symbol, the company currently only provides white characters (if the solder mask is white, then it needs to use black characters).
Pad plating
Refers to the PCB board surface exposed copper foil treatment, the company currently offers a variety of options, the specific reference http://www.gyxpcb.com/service/pcb/, the mainstream of conventional spray.
Solder resist coverage
Refers to the ink-covered area. This point should be highlighted and is often a controversial area. The company currently offers the following options: (1) Through-hole cover oil (2) Through-hole window (It should be noted that when the customer provides a gerber file, our company will handle it according to the document) (When engineers design with PCB software, please Define the type of hole).
test method
At present, the model will use all free testing services to ensure quality. For a simple single panel, it will not be tested and shipped! (Please carefully select the test method).
Copper foil thickness
Conventional copper foil thickness is 1 oz (35um). Our company provides a variety of unconventional methods. Please refer to the process capability page (the thicker the copper foil is, the higher the price).
