Common problems in the design of printed circuit boards
Saifon Technologies has been specializing for a long time in the design and manufacture of high—quality printed circuit boards for the needs of a wide variety of industries - from household appliances to the space industry. The introduction of innovative technologies and the latest tools allows us to create complex high-precision boards of exceptional quality. This allows you to significantly reduce the cost of production, while maintaining high performance. However, mistakes made by designers can significantly increase the manufacturer's costs or lead to the failure of the printed circuit board. This will certainly drop the company's image and reduce customer loyalty. We have collected the most common mistakes that even experienced designers make. Avoiding them will avoid unnecessary costs.
Acid traps
Avoid sharp corners when connecting conductive tracks. The fact is that a solution that is used for etching the printed circuit board can accumulate in such connection points. This can lead to the "opening" of the circuits. The easiest way to avoid the acid trap is to design boards using 90—degree angles. This type of error occurs in all types of boards, including when creating an aluminum printed circuit board. Therefore, before handing over the project, it is worth making sure once again that the routes intersect correctly.
Insufficient margin from the edge
If the conductive copper layer is located too close to the edge of the board, it can lead to its exposure. A conductor such as copper is susceptible to corrosion, which will certainly be followed by a short circuit. In addition, you can get an electric shock when your fingers come into contact with the copper edge. But this problem is easily solved. It is necessary to make sure that the circuit board is "cut off as it should" with the necessary indentation of the copper layer from the edge of the plate. It is recommended to specify the minimum indentation in all projects immediately in the   future, so as not to make such an error in the future. 0.3mm will be enough.
Placement of transition holes
It is not worth placing on the contact platform. Although it may seem like a great idea. After all, such a technique will save space and reduce the dimensions of the aluminum printed circuit board. However, this will only lead to the fact that during installation, the solder will simply leak through the holes. Today there is a method of placing transition holes in this way. But it must be used in  exceptional cases and very carefully. Therefore, if it is possible to avoid such a reception, we recommend doing it.
No soldering mask
It allows you to isolate the conductors. And thereby avoid their accidental contact with other components of the board. Its absence can lead to solder spreading and the formation of a jumper between the terminals. Which will lead to a closure in the future. This problem is especially common when designing small-sized boards with a small pin pitch. The designer needs to check the board design very carefully for the subject of this error. The company Saifon Technologies successfully applies a technology that allows you to refrain from the absence of a soldering mask.
Copper thickness
The issue with the choice of material must be resolved even before the tracing of the board. To create more powerful models of flexible printed circuit boards, you will need a thick layer capable of withstanding a high level of current load without overheating. The thickening of the tracks affects the allowable gaps. Therefore, it is necessary to accurately calculate the thickness of copper for a specific board. Otherwise, it may be necessary to re-arrange the tracks. It should be borne in mind that the thicker the material, the more expensive it is. An experienced designer must correctly calculate the thickness of copper so that in the future the board does not fail, but so that the customer avoids unnecessary expenses.
Thin conductors
Such a mistake has its consequences. Excessively thin connection of polygons will lead to their burnout under the influence of current flow. This will happen if the conductors are not designed for such a current load. Even if it is an "earth" polygon, it is necessary to double-check the width of the conductor. This is dictated by the fact that reverse currents flow through it. If the calculation is incorrect, the board will close.
Inefficient layout of elements
Modern electronics requires flexible printed circuit boards to get smaller and smaller. There is a need to use even smaller components and reduce the distances between them. Especially if it is necessary to mount elements with a large number of pins. The designer needs to adequately design the board so that in the future there will be no problems with its connection. In addition, if the dimensions of the elements are calculated incorrectly, this will lead to the fact that during installation they will simply break or be poorly soldered. In addition, it is by no means recommended to place several components that do not fit on the other side of the board. This will lead to a  its the strongest rise in price. It is better to spend more time for a more efficient arrangement of elements on one side of the printed circuit board.
Hole diameters
It is not worth designing boards with different hole diameters. This rule applies to  mounting and to transition holes. Different diameters will require the installation of tools of various sizes. This can lead to unnecessary expenses. And also to increase the time for manufacturing of a flexible printed circuit board. In addition, if you need to add mounting and transition holes, it will be easier to do because of their identical sizes.
Incorrect track geometry
The routes are responsible for the transmission of current signals between the components of the board. When calculating the thickness of the length of the tracks, it is necessary to take into account the speed and current strength. The width of the route depends on the amount of copper. Designers often choose a standard thickness, but it may not be enough when designing a more powerful board. The advantage of a large value of the thickness of the route is a lower resistance to current flow. Therefore, incorrect calculation of the geometry of the tracks can lead to an excessive rise in price and weighting of the board, or to a decrease in the necessary operational characteristics. In both cases, the client will not be satisfied.
Project flaw
Insufficient analysis of the board development process in   as a whole and shortcomings at  each of its stages in  individually can lead (or, more precisely, will definitely lead) to the detection of a large number of errors at the final stage. It is necessary to analyze and thoroughly check for compliance with the customer's requirements and the contractor's capabilities each circuit and the functions of the aluminum circuit board in all details. Because in such a responsible process, little things simply do not happen. Such a scrupulous approach will avoid the common mistakes that we have listed above. And   it can also significantly reduce the manufacturer's costs and reduce the order execution time: you will not have to make a new re-layout of the tracks or change their  geometry.
