What does PCB puzzle mean? Six Tips for PCB Puzzle

The PCB puzzle is only for the convenience of production.For sheet metal factories,their substrates are usually relatively large.They make many sheets at once and then cut them piece by piece.If this puzzle is mainly used for welding production,imagine a wooden board with large nails being welded one by one on an SMT machine the size of a car.
There are several definitions for PCB puzzles!
The convenience of plugins lies in their convenience for manufacturers to produce and save materials!The convenience of plugins is that customers need such a spelling,and you must do it according to your needs.The convenience of manufacturers in production lies in the convenience of V-shaped cutting,etc.The purpose of saving materials is to better utilize materials and not waste or leave too much edge material!For example,if you open a 34X41CM puzzle and use a material of 1.2 meters by 1 meter,it will be perfect.

Firstly,there is a puzzle question.We know that the main problem with jigsaw puzzles is saving production costs.The width of the PCB board is 260mm~300mm,which varies depending on the production line.Because we may have a lot of materials,in our processing equipment,one material gun corresponds to one module,so if the puzzle exceeds the range of the module,the processing speed will become very slow.
2.The outer frame(clamping side)of the PCB board should be carefully considered to ensure that it does not deform after being fixed on the fixture(V-shaped grooves are usually not allowed on this side).For the layout of parts,firstly,all directions must be consistent and there must be no mirroring,which can lead to coordinate positioning problems during the machining process.
3.At the edges(between the outer frame and inner small board of the puzzle board,between small boards),there should be no extension of connectors.If this situation occurs,it will prevent tool separation after welding is completed.
To ensure the position and level of the detection board,we need to set three or more positioning points at the edges of the board.By optical detection of these three points,the reference coordinates of the entire machining process and the levelness of the sheet can be obtained.The correct method is to set a distance of 5 millimeters from the edge,and the distance in the stroke direction is inconsistent(to distinguish the direction of entry):[When setting a reference positioning point,usually leave a non resistance area 1.5 millimeters larger than it around the positioning point.].
5.Each small board must have at least 3 positioning holes,3 6mm holes,and no wiring or patching is allowed within a 1mm range of edge positioning holes(to prevent misjudgment).PCB boards are mainly used to save production and processing costs(increasing machine processing speed several times).Unreasonable design can lead to problems in the later stages.You can observe more carefully to prevent problems from occurring.
