The printed circuit board design can be very difficult and challenging job. Here at Tektron Genesis we provide you 10 important tips for selecting right PCB components for PCB design.
1. Bill of Materials – Helpful for Virtual Parts
The main task of BOM will support you create the virtual parts list when you will require it. Also helpful to allow the review of virtual parts in the designing section. The power and ground signals might be included in virtual parts. These parts will be definitely included in the schematic environment, won’t be a move to the layout section. If used only for simulation purposes that parts are shown in the virtual section, otherwise replace with the parts having footprints.
2. Reference Designators – Reviewing of the BOM
The main role of reference designators is to help in the arranging and reviewing the BOM, ensure that are instantly numbered.
3. Check BOM Data Report
Ensure you have complete BOM data and review it. Before you move on to the design section, check out all parts are included and make sure nothing is missing.
4. Basic Design outline
Before releasing costly prototype design, the design outline is helpful to give a basic idea of component’s position. Also, this will give an essential sense of the positioning of the parts, the required height and whether the entire plan will work or not – comprehensively, and also electronically.
5. Need Proper Ground Planes
First, you make sure the design appropriately bypass capacitors and ground planes. When depending on the application of the PCB, You will require appropriate capacitors, in terms of included size and frequencies. Also, your design should need proper good ground planes and avoid the capacitors.
6. Think about Footprint
When you’re moving on to the schematic drawing phase, consider Footprint and Land pattern choices that should be made in the design stage.
7. Think about Land patterns
Land Patterns is the setup of pads in SMT or Through-hole technology. Their main use is to physically attach and electrically connect a component to a PCB. The land design on a circuit board matches the setup of leads on a component.
8. Choosing components
This tip is important for PCB design. Choose the appropriate component because some components have a limitation of height so consider about the covering of the PCB on both its top and bottom sides.
9. Choose Surface Mount Technology or Plated Through Hole?
During the design process, component choices can be changed. Choosing which component will be Surface Mount Technology and Plated Through Hole in the design process can help the whole arrangement of the PCB. While thinking about component selections, there will be issues as far as costs, accessibility, component area density and power dissipation among other things, which will affect your design.
10. Review Spare gates
Generally, the majority of spare gates should have the inputs connected to signal to avoid the inputs from floating. Ensure you review any spare gates goal that are unwired input sources can be effectively connected if required. At times, if the input sources are left to float, the entire system may not work correctly.
Final Note: Always keep in mind, a few times spent in preparation at the initial phases – specifically when it comes to selecting components –this can help very much when it comes to the production phase and last use for the PCB. Your selection of parts can (and frequently will) change through these procedures so be open and responsive to where your design is taking you. Once more, the procedure can be natural and electronic.
