First things first – before starting your printed circuit board or PCB assembly adventure with us, you must first set the specific goal that you want to accomplish. Like all goals in our life, we must know what is the whole point or purpose of the project that we want to undertake. Don’t worry with parts, relevant supplies and production. We can assist you with that, but you need to know your reason first and set your goals.
Armed with the reason in your mind and heart, you can then visualize the design that you want to do. The technical aspects of your design may be complicated or simple, but we can definitely help you with in the PCB assembly process. Consider the final product you want to make and the aspects and unique characteristics of that creation that you want it to have.
With those considerations in mind, you can now start doing the legwork. Start drafting your design. Start listing all the basic details and specifications of your intended output and design. This is a great starting point, then start listing all the special configurations and the materials or supplies that you need in order to make it a reality. You can either do this on a computer or in a notebook. This process will transform your project from an idea inside your head to an idea on the screen or paper that you can actually modify, plan, and think about.
The actual work starts when you create, analyze and optimize your design in computer-aided drafting or CAD. It is vital to put labels in the numerous components that are incorporated in your own design. This is to make your work more efficient and your design decisions less cluttered in nature.
To help you with the labeling of the components of the design for efficient assembly, here is a little review.
The following letters are the default designators for the usual passive components.
Resistor is represented by R. Capacitor is signified by C. Inductor is indicated by I. Diode is represented by D. Letters M and Q are used to signify transistors (MOSFETs are M while BJTs are Q). M can also mean motors for designs that involve motors. Transformer is referred by T or XFMR.
Switch can be represented by S or SW. Crystal oscillators are signified by XTAL. Subcircuits are represented by X. Here is the other parts: U or IC stands for integrated circuits, TP represents test point, JP stands for jumpers, J or P are for jacks or plugs, F is for fuse, FD represents fiducial, BT or BAT for battery conductor or battery, X are for other parts not mentioned. Take note that in PCB design and assembly, consistency in the letters that you use and logical positioning of the relevant labels are the keys to attaining a clutter-free design.
Now that you are familiar with the labels, you can start drawing your design. It is very important to start with components with a specific physical. Examples of these are sensors or connectors that should not be blocked. After them, you can place your ICs. It is good to start with the bigger ICs then the smaller ones. Work smart and keep your ICs oriented in one direction. After ICs, place the supporting devices on the board, such as capacitors, diodes, resistors, among others. Remember that it is important to make sure that you leave adequate space for the markings and annotations on the board.
With that process finished in your PCB assembly adventure, you can proceed to making the connections. There are two ways to do this. For designs with high frequency signals, start by routing them first. If your design does not have high frequency signals, start by routing your power traces.
After this process, we can help you with a quick turn prototypes for testing and verification of your designs. After this, your project can be fulfilled through our high-quality PCB fabrication and production that will meet your specifications with on-time delivery at an unbelievably low price. After your hard work in PCB designing, fulfillment of your PCB assembly goals should be entrusted with the most experienced PCB supplier like us.
