The reverse costing analysis is conducted in 3 phases:
Teardown analysis
• Package is analyzed and measured• The dies are extracted in order to get overall data: dimensions, main blocks, pad number and pin out, die marking• Setup of the manufacturing process.
Costing analysis
• Setup of the manufacturing environment• Cost simulation of the process steps
Selling price analysis
• Supply chain analysis• Analysis of the selling price

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimates completed by industry experts.
Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on the manufacturing cost (if all parameters are cumulated)
These results are open for discussion. We can reevaluate this circuit with your information. Please contact us:USA Office
