What is the definition of pcb puzzle
The pcb jigsaw is only for production convenience. For the board manufacturer, his substrate is generally relatively large. Many boards are made at one time and then cut out one by one. If the jigsaw is mainly used for welding production, Imagine a board with large fingernails one by one welded to an SMT machine the size of a car.
Pcb puzzle has several definitions! Convenient customer plug-in is a convenient manufacturer to produce by itself is a material saving is one! Convenience plug-in is what customers want to fight like this, and you have to do it as required. It is convenient for manufacturers to produce V-cuts and so on. To save material is to use the material more perfectly without wasting or leaving too much waste! For example, the material of 1 meter 2 by 1 meter is perfect when you open a 34X41 CM puzzle.
The method of PCB jigsaw includes a method of creating a finished sheet jigsaw worksheet and a blank sheet jigsaw worksheet by using an Excel program stored in a known computer, and a method of using the above worksheet. The finished board puzzle worksheet is used to complete the finished product. The slab process on slabs is at the same stage. Each column of the completed tablet worksheet is used to place data of the same category of different categories of tablet solutions or Excel internal function calculation formulas for that data. Cells are used to place different categories of data for the same puzzle scheme or Excel internal function calculation formula for this data. The specific method of creating a completed puzzle worksheet is:
(1) Start the Excel program stored in a known computer, create a new workbook, and then select a worksheet;
(2) The name of the worksheet with cells in the input table:
(3) Use a row of cells in the table as the title of the worksheet, and enter the category name of the data in the column of each cell;
(4) Create a data input area:
(5) Create a data operation area
(6) Create a data output area
(7) Create a puzzle calculation area
(8) Create indirect output area Use Excel’s internal search and reference functions to reference all the data in the worksheet of the puzzle operation area and place it in the indirect output area.

PCB puzzle skills
PCB puzzles are often done by PCB factories. What should I pay attention to when jigsaw? What are the rules of PCB puzzles? To summarize for you:
First, regarding the problem of jigsaw puzzles, we know that the main problem of jigsaw puzzles is to save production costs. For PCB panels with a width of ≤260mm ~ 300mm, it varies according to different production lines. Because we may have many materials, one processing gun for each processing equipment corresponds to one module, so if the puzzle is beyond the scope of the module, the processing speed will become very slow.
The outer frame (clamping edge) of the PCB puzzle should be carefully considered to ensure that the PCB puzzle is not deformed after being fixed on the fixture (usually V-grooves are not allowed on this side). The direction should be consistent and no mirroring will occur, which will cause processing positioning problems.
Secondly, there must be no protruding connectors on the edges (between the outer frame of the puzzle and the inner plank, and between the plank and the plank). If this happens, the tool will be prevented from separating after the welding is completed.
Guarantee In order to ensure the position and level of the test board, we need to set more than three positioning points on the edge of the test board. Through optical inspection of these three points, the reference coordinates and plate height of the entire process can be obtained.
The correct method is: the distance from the edge is 5mm, and the direction of travel is also different when the direction of travel is inconsistent (the direction of travel is easy to distinguish): [When setting the reference positioning point, usually leave 1.5mm of the soldering zone around the positioning point is similar Or other similar pads]
There must be at least 3 positioning holes on each small board, 3 ≤ aperture ≤ 6 mm, wiring or patching is not allowed within 1 mm of the edge positioning holes (to prevent misjudgment). The main purpose of PCB puzzle is to save production and processing costs (which will make the processing speed of the machine several times faster). Irrational designs will be full of problems in the future. You can carefully study to prevent problems.
