Project background
1. This 6 Layer HDI Rigid-flex board is used in the medical field, where there is a demand for high-density electronic components and a shortage of components.
2. Due to the different thicknesses and mechanical properties of hard boards and soft boards, it is difficult to mass-produce HDI multi-layer circuit boards.
3. For high-density circuits and multi-layer structures, the design rules are very strict, including line widths, aperture sizes, inter-layer distances, etc. There are many details that need to be confirmed.
Project challenge
Ÿ The component cycle is long and takes at least 18 days, which does not meet the customer’s urgent delivery needs.
Ÿ The structure of this board is relatively complex, and the process needs to be optimized to improve the product yield rate.
How to serve?
(1) The engineer suggested changing the PTH holes to blind stacked holes to optimize the production process and reduce the probability of scrapping.
(2) Test the two bending areas of the soft board in advance to ensure that no bending problems will occur under specific circumstances.
(3) Customers send us some components with long lead times, which greatly reduces the delivery time of components.
(4) Professional sales will follow up on the order status and update the production progress at any time. If there are any questions, we will immediately feedback them to the customer for confirmation.
Results and Benefits
Production and patching were completed within the expected delivery date, and subsequent customer testing was also successful. Customers' new products can also be quickly introduced to the market.
