7 Technical Requirements For The Design Of Printed Circuit Boards
By creating tracks, paths and clearances that are very dense with HDI, your PCB can still perform excellently. When it comes to high current, high voltage design, you need to pay attention to controlled impedance routing, differential pairs, as well as leakage, play and width. Understanding the processes involved in the production of a circuit board will help you make better design decisions, as well as know what processes and methods your manufacturer will use.
Choose the right techniques, components and manufacturer; use excellent welding skills and project files and avoid the common PCB issues mentioned above.

So what are the key points for designing PCBs to make your prototyping process faster? When other transmission standards and drive currents are selected, the corresponding impedance will vary. When designing high-speed circuits and logic, for some important signals, such as clocks, control signals, etc., we recommend adding resistors on the source side. Finally, it’s important to choose the right package size while you’re in the board’s design phase. A PCB master only opts for smaller packages if there is a good reason for this; Otherwise, lean towards larger options.
You can reduce the EMI effect by separating the control ground planes and the ground planes for each phase of the power supply. If you place the base in the middle of the layer structure, you must set a trajectory as impedance. And remember to ALWAYS consider the RF part first and foremost, as it carries a high-frequency signal and if you put it last time, you won’t have enough space to house it and ultimately let your design fail. To avoid creating a nightmare of multiple groundings and voltage drops, include a special mass plane in your circuit board design. The base can be a large layer of copper or, better yet, a complete surface on a multilayer plate. With the ground plane in place, all you have to do is connect the components that need to be grounded to the aircraft via tracks.
Different companies use different production machines that used to have different tolerances for the same 0805 package. Therefore, the standard package footprints are slightly larger pcb design company than necessary. For any electronic product, whether it’s a complex mobile phone or another simple inexpensive electronic toy, circuit boards are an essential component.
You still need to make sure that you have enough space between the components so that it is possible to weld and assemble the board. Quality software often makes it easier for you to virtually see where the components will be located. Add enough space to work on the board if necessary, but still keep it relatively small. Any power failure can lead to a shutdown of the installation, which costs a significant amount of time and money.
In a product development cycle, design cost management is a major issue, and PCB is the most neglected and expensive part of the BILL of materials. The PCB costs much more than any other part used in a circuit, so reducing the PCB will not only reduce the size of our product, but in most cases also reduce the cost of production. But how to reduce the size of a PCB is a complex question in the production of electronic products, because the size of the PCB depends on some things and has its limitations. In this article, we will describe the design techniques for reducing the size of the PCB by comparing the trade-offs and possible solutions. To be error-free in design design, design engineers use a number of techniques.
This is because the different resistance values of the tracks can cause different voltage drops. The design of a circuit is common among designers where they try to integrate as many components as possible to complete the design. This is not really necessary, as many modern and cost-effective MCUs on the market are quite capable of replacing parts, making their design less bulky and cost-effective. Combining correct analog parts or digital chips with a microcontroller will reduce the size of your circuit and increase efficiency quite drastically. A disconnection capacitor is connected in parallel connection near the power supply in the circuit design process to deliver pure DC power supplies.
If there are parts that require long lead times, they can be ordered in advance and sent to the board assembly supplier. The assembly supplier can also handle the procurement of the most available parts so that each part is ready and waiting when your boards are ready to be assembled. Sometimes the only package available for a particular device is a lead-free PGI. However, plates used for military projects should generally be assembled with conventional lead solder, according to government requirements.
If there are problems in your bill of materials, the assembly house will suspend the project until the problems are resolved with an engineer. One way to make sure your BOM is up to date is to check it when there’s a change in your design. When you add new components to the schematic while the design is in progress, make sure that you have also updated the BOM with the correct part number, description, and component values. During the design process, the technician may change a part due to long lead times, size, or availability and forget to update the BOM with the new part number. The board designer should talk to the circuit designer and engineers to see if the component size can be reduced, creating additional board space. Before establishing the first track, you need to find out the specifications of the manufacturer of your preference.
