Drill Sizes
Drill sizes are very important when making circuit boards. If holes are too big or too small, parts will not fit. The boards might not work right. Manufacturers use CNC machines to drill holes in the right places. These machines use strong drill bits made of tungsten carbide. The bits have special shapes to make smooth holes. Machines follow your design using software that checks for mistakes before drilling. After drilling, tools check if the holes match your design. Industry rules like IPC-2221 help set the right hole sizes. Always ask your manufacturer how they make sure drill sizes are correct.
Tip: Getting drill sizes right helps stop plating voids and solder bridges. These problems can make boards fail.
Trace Widths
Trace widths decide how much current can move through your board. If traces are too thin, they can get too hot or break. Manufacturers use CAD and CAM tools to set trace widths from your design. These tools look for mistakes and make sure traces are safe. Automated Optical Inspection checks trace width after the board is made. Rules like IPC-2222 say how wide traces should be for safety. Good trace width control also helps stop signal problems like crosstalk or signal loss. You should talk about trace width rules with your manufacturer before you start.
Trace Width (mm) | Max Current (A) | Use Case |
|---|---|---|
0.15 | 0.5 | Signal lines |
0.25 | 1.0 | Power lines |
0.50 | 2.0 | High-power areas |
Component Sourcing
Where you get parts from changes the quality and price of your boards. You want to use good parts that fit your design. Manufacturers work with trusted suppliers to get parts. They check if suppliers have the right papers and test parts to avoid fake or bad ones. Good sourcing means using certified parts that work well under stress. Manufacturers often use just-in-time systems to keep parts fresh and waste less. They also use more than one supplier to avoid delays if one has problems. You should ask your manufacturer how they pick and check parts.
Work with trusted suppliers for better parts.
Use certified parts to lower the chance of failure.
Use more than one supplier to avoid supply problems.
Note: Careful sourcing helps you avoid delays, save money, and get boards that last longer.
