ADVANCED HDI PCB FABRICATION & ASSEMBLY
With top advanced capabilities of competitive PCB market, we got high reputations of offering HDI PCB (printed circuit boards). HDI PCBs are the circuit boards with higher wire density than standard criterias. HDI PCBs appear thinner lines and spaces, smaller vias and higher connection pad density, which are commonly used for high spacing and precision required devices and system cards.
HDI PCB DEFINITION & APPLICATION
Under the premise of electronic products getting multifunctional and complex, circuit component connection distance is getting smaller and singal transit speed higher. Subsequently, number of connection wires becomes more and line length between pads shortens, which require to use high density wire configuration and tiny via to comply with design goals. In terms of electrical requirements for high speed signal, the circuit board must be provided with the AC characteristics of impedance control, high frequency transmission capacity and low unnecessary radiation (EMI). Using stripline, microstrip structures, design of multilayers becomes necessary. To reduce the quality problem of signals transmission, it’s required to use low dielectric coefficient and decay rate of insulating material to facilitate the miniaturization and arrays of electronic components packaging. Also, printed circuit boards increase density to meet this demand. BGA (Ball Grid Array), CSP (Chip Scale Package) and DCA (Direct Chip Attachment) parts push printed circuit boards to the unprecedented high density level. That’s why HDI PCBs become more popular. Currently smartphone, wearing devices, compact controllers are widely using HDI PCBs.
Electronic design continuously improve performance in attempts to reduce its size. In terms of small portable products from mobile phones to smart weapons, 'small' is the permanent pursuit. High density integration (HDI) can make the end product design more compact and meet higher standards of performance and efficiency. HDI is widely used in mobile phones, digital (photo) cameras, MP3, MP4, laptop computers, automotive electronics and other digital products. Among them, mobile phone takes biggest portion. HDI PCB boards laminate in build-up manufacturing. High HDI PCB boards are mainly used for 3G/4G mobile phones, advanced digital cameras and IC loading board.
