Multilayer Circuit Board IPC-A-600 is valid for PCB or Printed Circuit Boards

... where the solder mask is to be removed are placed in direct contact with both sides of the panel. The panel is then exposed | MULTILAYER CIRCUIT BOARD | to UV light. The amount of light used is controlled by an integrator. Printing is done with a semi-automatic dual drawer printer. While one drawer | MULTILAYER CIRCUIT BOARD | is being loaded with a panel and phototools, the other is inside the machine being exposed. This dual drawer printing system runs at the same | MULTILAYER CIRCUIT BOARD | rate as the screen printer to insure continuous flow. Develop LPI Mask After the panel has been exposed, it is placed in a vertical developer. | MULTILAYER CIRCUIT BOARD | The unexposed solder mask is dissolved in a high pressure spray of developing solution. The solution temperature, concentration and conveyor speed control the development process. | MULTILAYER CIRCUIT BOARD | The developer solution concentration is maintained by a feed and bleed system controlled by pH. After development, the panels are rinsed and dried. Cure LPI | MULTILAYER CIRCUIT BOARD | Mask As panels exit the solder mask developer, they are automatically loaded into the conveyorized ...

... layers, and explained to the fabricator in a README file. The idea here is that the fabricator should be able to quickly understand what | MULTILAYER CIRCUIT BOARD | each file is and where it goes in the stackup. If you wish to continue using Gerber data, switch to 274X. 274D is obsolete; the | MULTILAYER CIRCUIT BOARD | external aperture information is more cumbersome and difficult for fabricators to deal with because they have to worry about translators and parsers to read the | MULTILAYER CIRCUIT BOARD | aperture table information. As a result, aperture data might be misinterpreted. Worse, someone might have typed in the information manually - and erroneously. By contrast, | MULTILAYER CIRCUIT BOARD | in 274X, all the aperture information is contained within the Gerber file, which can be read by most CAM tools automatically. For netlists, IPC-D-356 is | MULTILAYER CIRCUIT BOARD | the preferred format for fabrication. It's widely used by many of the bare-board test-fixturing machines and is one of the only true ways to identify | MULTILAYER CIRCUIT BOARD | power-to-ground shorts. With the information in this format coming directly from the ...
