How can Chip-on-Board lower costs of production?? Why do use and throw products prefer Chip-On-Board?? https://learn.sparkfun.com/tutorials/how-chip-on-boards-are-made/all I was going thru the above link . My primary understanding was chip on board offer dead cheap manufacturing process. But it looks like during manufacture chip board undergo many different process. How is it cost effective than using a single uC chipset and wave soldering ?? no separate process needed My assumption is that chip on boards are pre-programmed controllers. Please educate |

The cost of the packaging itself becomes significant in high-volume applications. |

Yep. Event the cost difference between WLCSP and BGA or QFN is significant in large quantities. It may be 1/3 of the cost of the whole device. I don't think there is a huge cost difference between WLCSP and COB, but I imagine board cost is higher for WLCSP. And most modern device can be programmed in-circuit, so it is not a big deal. |
