What is the definition of pcb puzzle? pcb puzzle is only for the convenience of production. For the board manufacturer, his base material is generally relatively large. He makes many boards at a time and then cuts them one by one, if the puzzle is mainly used in welding production, imagine a board with a large nail cover to weld on a SMT machine as big as a car. There are several definitions of pcb puzzle! Convenient customer plug-in is one, convenient manufacturers to produce their own is a saving material is one! The convenience plug-in is what the customer requires, and you must do it as required. The manufacturer's convenient production is convenient for V cutting. Saving materials is to use materials more perfectly without wasting or leaving too much leftover material! For example, with a material of by, you can open a 34X puzzle. What does pcb puzzle mean _ pcb puzzle skills PCB puzzle method, including the application of Excel program stored in a well-known computer to create a finished board worksheet and a blank board worksheet and the use of the above worksheet; The finished plate puzzle sheet is used to complete the process of the finished plate on the blank plate, each column cell of the finished plate puzzle worksheet is used to place the same category of data of different blank plate puzzle schemes or the Excel internal function Calculation Formula of the data, each row of cells is used to place different categories of data of the same puzzle scheme or Excel internal function calculation formula for the data. The specific method for creating the finished puzzle worksheet is as follows :(1) Start the Excel program stored in the well-known computer, create a new workbook, and select a worksheet; (2) Enter the name of the worksheet with a cell in the table :(3) Use a row of cells in the table as the header of the worksheet, and enter the category name of the data in the column in each cell; (4)Create a data input area :(5)Create a data operation area (6)Create a data output region (7)Create a puzzle operation area (8) Create an indirect output area use Excel internal search and reference functions to reference all data in the worksheet of the puzzle operation area and place them in the indirect output area. What does pcb puzzle mean _ pcb puzzle skills PCB puzzle is a common thing for PCB factories. What matters should be paid attention to when assembling? What are the main principles of PCB splicing? For you to summarize as follows: First of all, the problem of splicing, we know that the main problem of splicing is to save production costs. For PCB splicing width ≤ 260 ~ 300, depending on the production line. Because we may have a lot of materials, the processing equipment itself corresponds to a module, so if the puzzle exceeds the range of the module, the processing speed will become very slow. The outer frame of the PCB puzzle (Clamping edge) Careful consideration should be taken to ensure that the PCB panel will not deform after being fixed on the fixture (Generally, it is not allowed to open a v slot on this side) For the arrangement of components, the first orientation should be consistent, and there should be no mirror image, which will cause the coordinate positioning problem of processing. Second at the edge ( Between the outer frame of the puzzle and the inner small board, the small board and the small board) There cannot be a situation where the connector extends out. If there is such a situation, it will prevent the tool from dividing the plate after welding is completed. In order to ensure the position and level of the detection plate, we need to set more than three positioning points on the edge of the plate, and detect these three points by optics, the reference coordinates of the whole machining and The levelness of the plate can be obtained. The correct approach is that when the distance is 5mm from the edge and the direction of travel is inconsistent, the spacing is different (Easy to distinguish the direction of entry):【 When setting the reference positioning point, it is usually set aside around the positioning point by 1. 5 mm non-solder mask area, no similar pads or other similar] There must be at least three positioning holes in each small plate, 3 ≤ aperture ≤ 6mm, and no wiring or patch is allowed in the edge positioning hole 1mm (Prevent false judgment). PCB splicing is mainly to save production and processing costs (Will make the machine processing speed several times faster) Unreasonable design will make the later stage full of problems, you can take a closer look to prevent problems. The first is the problem of the puzzle. We know that the main problem of the puzzle is to save the cost of production. For PCB splicing width ≤ 260 ~ 300, depending on the production line. Because we may have a lot of materials, the processing equipment itself corresponds to a module, so if the puzzle exceeds the range of the module, the processing speed will become very slow.
