Understanding Manufacturing Tolerances on a PCB
Splet· Extremely Tight Tolerances. Conventional PCB tolerances of +/- 0.005” or +/- 10% for mechanical & electrical properties could be inapplicable to MCPCBs. When attempting to combine high-speed functionality with the metal core printed circuit board, tight tolerances of +/- 0.001” may be necessary. SpletPCB quality Clean, flat, plated, or coated solder land area. Attachment surface must be clean and free of solder-mask residue. Placement accuracy Tight tolerances are not usually required. QFN and SON packages self center as long as a major portion (more than 50%) of the lead finger is in contact with the solder-paste-covered land area on the ... Splet17. jul. 2024 · As you can see, there are a number of ways to constrain the geometry. The cross-hair positional target is the most widely used in PCB layout documentation; generally for hole locations. Flatness, Parallelism and Runout are a few other common geometric tolerances applies to PCBs. There are reasons for any of them to show up on a drawing. ron white oklahoma casino
