Rigid-flex Circuits Stackup

Rigid-flex circuits is a complicated product that demands a lot of interaction between the PCB provider and the customers. Like other complex products, early discussions between Hemeixinpcb and the designer is necessary to optimize the design for manufacturability and to optimize costs. Hemeixinpcb supports rigid-flex circuits boards for higher volume requirements.
Please send email to sales@hemeixinpcb if you need further information or assistance, we are happy to help you.

Rigid-flex circuits technology using ELIC is receiving increased emphasis in new product designs to achieve:

Higher volumetric interconnection of components and structural featuring within the PCB.

Elimination of traditional connectors and ACF bonding FPCs to rigid PCBs within herent cost and reliability issues.

Laminate, Materials, Chemistry, and Equipment suppliers roadmaps are on track to provide compatible LF/HF materials and µvia process systems for Rigid-flex to move to mainstream.

Global market demand for Smartphones and Tablets have accelerated (and funded) the technology development of stacked µvias and associated mass production infrastructure.

Filled via rigid-flex circuits technologies are now essential rigid-flex circuits PCB fabrication processes to achieve high SMT yield and reliability for Area Array IC package and fine pitch passive components assembly.

Filled and stacked µvia sequential processing is maturing to very high yields.

Quick turn PCB

图片
Today’s OEMs are tasked with supplying higher performance products that require increasingly complex printed circuit boards (PCBs) while reducing cycle times and bringing products to market faster. This drives the need for quick turn PCB fabrication regardless of the complexity of the board, backed by advanced manufacturing processes and high mix production capabilities. Hemeixin Electronics Co.,Ltd, through its Quick Turn Around (QTA) capability, provides a wide range of prototype/new product introduction PCBs in the early design phase so that customers can stabilize new designs and then get them to market quickly. “Due to an increase in demand in the defense/aerospace, IT/supercomputer, medical and ATE markets, we have created a separate and dedicated QTA fabrication line with its own set of equipment, processes and operations personnel,” said PPC Manager, Director of QTA Operations at HemeixinPCB. “We have invested in QTA capability in order to provide 1 to 10...
