We have spent substantial effort in developing this product and it is one of the first of its kind in the industry with a unique internal construction. Having the internal photos easily available to other competing manufacturers would negate the advantage we have achieved by developing this product. Not protecting the details of the design will result in financial hardship. The circuit board and bond wiring and all internal components are not accessible because they are enclosed by the molding material which fills all empty spaces (just like any other IC). Integrators and users do not have access to the internals of the module, due to the fact that the module is completely molded and mechanically removing the molding material will destroy the module and break the parts in it. Please refer to the provided photos for the filing, showing the module’s packaging. In addition, our design files, including internal photos, are never shared with our downstream customers, not even under NDA. Consequently, the document(s) under the scope of this letter are eligible for the Long Term Confidentiality, in accordance with KDB publication 726920 D01 II. 3) a), without being subject to PAG. Should there be any query regarding this request, please do not hesitate to contact the undersigned. Thank you for your attention to this matter.
