Reverse Engineering PC Board Level 3 Drawing

Reverse Engineering PC Board Level 3 Drawing objective

Reverse Engineering PC Board Level 3 drawings are the result of the PC Board reverse engineering process and should contain the documented parameters necessary to produce the selected candidate.

Preparation

One of the final results of a PC Board reverse engineering process should be the preparation of a drawing to be used for competitive procurement.

Content

A reverse engineered item may result in the use of several types of drawings. Level 3 drawings consist of engineering drawings and associated lists which provide sufficient definition for manufacturing and production without resorting to additional product design efforts, additional design data, or recourse to the original design activity. Level 3 drawings should:

1. Provide requirements which permit replication of the original PC Board except for characteristics changed as a result of value engineering, product improvement and other formal design change actions;
2. Provide the engineering data for support of quantity production; and
3. Provide the necessary data to permit competitive procurement.

Considerations

Based on sound engineering judgment concerning the complexity and engineering sophistication of the design, the types and number of drawings required to satisfy the function should be prepared. The engineering drawings should consider the following:

1. Details of unique processes,
2. Performance ratings,
3. Dimensional and tolerance data,
4. Critical manufacturing assembly sequences,
5. Input/output characteristics,
6. Diagrams,
7. Mechanical and electrical connections,
8. Physical characteristics including form and finish,
9. Details of material identification,
10. Inspection, test, and evaluation criteria,
11. Calibration information,
12. Quality Control data,
13. Interface characteristics,
14. Critical safety items,
15. Electrostatic discharge sensitive items, and
16. Part marking items.

Drawing media.

Reverse Engineering PC Board Level 3 Drawing should be prepared on the media and formatted specified by the cognizant command. Pre-printed format paper and designated blocks of drawing numbers may be requested from the cognizant command.
