IPC-6012 sets performance standards for rigid printed circuit boards, while IPC-A-600 defines criteria for their acceptability, ensuring comprehensive industry guidelines.
The query should be: “Which standard should be followed, IPC-6012 or IPC-A-600? Read More »
The maximum warpage of IPC-6012, SMB-SMT circuit boards is 0.75%, with other boards not exceeding 1.5%. The warpage allowed by electronic assembly factories is usually 0.70-0.75%, but some boards require less than 0.5%. Warpage prevention methods include proper prepreg arrangement, baking the board before cutting, and paying attention to warp and weft directions during lamination and cutting. Warped plates can be treated by hot pressing and baking.
