Producibility Study of Reverse Engineering PCB target

The following areas should be considered when performing a producibility study of PCB Reverse Engineering:

1st point is Dimensions/tolerances

Tolerance analysis should be performed to ensure that the dimensional limits are sufficiently controlled so that the form, fit and functional requirements are met, and to minimize any potential manufacturing difficulties in the machining, forming, assembly, and inspection operations. The maximum tolerance allowances should be determined to permit manufacturers to use alternate fabrication techniques to minimize costs. American National Standards Institute (ANSI) Y14.5M may be used as a guide for dimensioning and tolerancing.

2nd thing is about materials applied for construction of central locking system PCBA copy. The materials specified should be reviewed for impact on availability, cost, producibility, and function of the part. A range of materials equivalent in strength to the material to be used in the prototype should be specified to permit bidders to estimate manufacturing costs based on their best in-house process.

3rd point is about Heat treatment: The capability of materials to respond to specified heat treatments should be verified and specified. SAE-AMS-H-6088 and SAE-AMS-H-6875 may be used as guides.

Finishes refers as the 4th point need to be taken into consideration. The impact of finishes on function and cost should be evaluated. Different surface finish method on PCB Board after reverse engineering. The most economical finishes that will satisfy the functional requirements should be specified. If machine finishes are required, the highest roughness acceptable should be specified for the designed function.

5th, let’s talk about Clean and joining methods:  The proper joining methods, such as mechanical fasteners, metallurgical welding, brazing, soldering, and chemical adhesives, should be specified and evaluated for applicability, ease of access during the joining process, and alternate method of joining for cost reduction. The following documents may be used as guidance:
