![]() ![]() To save time in your future projects, you can add this parameter to your parts in your CAD software. Just choose the part you need and copy/paste its part number. Simply download this file, it has the list of all parts available with them and their details. You can use this part number to accurately identify the part you need. JLCPCB has a large stock of parts (more than 30,000) and each part has a part number. The last column is LCSC part number, now this can really help you speed things up and get accurate results. You should be aware of common SMT sizes like 1206,0805,0603 etc. The next one that is the Footprint or package is also very important because SMD parts come in various sizes(packages) so the assembly staffs should know which package would fit in your PCB. Next column is the Designator, that means on which position this part should be placed and soldered. BOM file is a simple text file in comma separated form (csv) but you can also make it in MS Excel or other spreadsheet programs.Īs you can see in the above BOM file, we have first column Comment where we should describe the parts in as much detail as possible, the most important being the value of part say 0.1uF but you should also include tolerance, maximum voltage and other information so that the production staffs can pick the best possible parts for your project. ![]() This information is present in the BOM file and is very important for assembly work. ![]() But the manufacturer should know what value capacitor or resistor is placed at that location. For example, PCBs have positions like C1,R1,T1 etc. The BOM or Bill of Materials file tells the manufacturer which components is installed at which position. In this tutorial, we will tell you about the steps to generate BOM(Bill of Materials) and CPL(component placement list, as known as a Centroid file/Pick and place file) in Altium Designer. How to generate Bill of Materials and Centroid File from Altium ![]()
