The contribution to not only the variety of ICs

Chinese tax policymakers made various efforts in the past to drive domestic innovation and increase the economy’s competitiveness in high-tech sectors. To this end Electronic Components Distributor, the integrated circuit (IC) and software sectors have benefitted coming from a series of corporate taxes (CIT), VAT and import tax incentives since 2012.

In recent years, global trade restrictions have impacted the flow of high-end components to China, therefore policymakers have further enhanced these incentives to aid domestic manufacturing of these components.

An interim method is to solder the standard packaged rigid IC with a (usually stiffened) flexible substrate. Such circuits are often referred to as flexible printed circuits (FPCBs) despite having etched interconnects. Unfortunately, mounting a packaged IC substantially impedes flexibility and removes the chance of R2R manufacturing.

One option would be to use bare dies, an approach that has been used for years in RFID tags. These possess a small (< 1 mm2) IC attached at two points utilizing a conductive adhesive with an antenna. However, this application avoids 2 of the difficulties linked to adding larger, more capable ICs. Firstly, the ICs are incredibly small that their flexibility is actually irrelevant at any realistic bending radius. Secondly, large attachment pads are viable since only two electronic connections are important.

A volume of PMICs, together with less sophisticated ICs and discrete components, constitute the energy supply and management circuitry and are also largely in charge of the effective treating these tasks. These PMICs range from the battery charger and main system power management unit as well as separate PMICs for other tasks. Due to the complexity and demands on the ability management circuitry, these characteristics need to be based on specialized PMICs that control power management in a system level instead of simple on-chip management.

Given the amount of PMIC devices, the contribution to not only the variety of ICs but also to some smartphone’s Bill of Materials (BOM) is rather significant. Some reports show an average smartphone design could possibly have $8 price of PMICs beyond a total BOM expense of $42 with the main PCB IC content (excluding DRAM and flash memory) – near 20%. For a tablet, the PMIC price is around $20 away from a $50 total ADI Analog ICs. Therefore efforts to reduce the overall area size and hence tariff of the PMIC could have a significant affect overall BOM cost.
