HDI PCB Introduction

-Definition

HDI PCB is defined as a printed circuit board with a higher wiring density per unit area than a conventional PCB. They have much finer lines and spaces, smaller vias and capture pads, and higher connection pad density than employed in conventional PCB technology. HDI PCBs are made through microvias, buried vias and sequential lamination with insulation materials and conductor wiring for higher density of routing.

-Applications

HDI PCB is used to reduce size and weight, as well as to enhance electrical performance of the device. HDI PCB is the best alternative to high layer-count and expensive standard laminate or sequentially laminated boards. HDI incorporate blind and buried vias that help to save PCB real estate by allowing features and lines to be designed above or below them without making a connection. Many of today's fine pitch BGA and flip-chip component footprints do not allow for running traces between the BGA pads. Blind and buried vias will only connect layers requiring connections in that area.

Where does the resin material come from in ABIS?

Most of them are from Shengyi Technology Co., Ltd. (SYTECH), which has been the world's second-largest CCL manufacturer in terms of sales volume, from 2013 to 2017. We established long-term relations of cooperation in 2006. The FR4 resin material (Model S1000-2, S1141, S1165, S1600) is mainly used for making single and double-sided printed circuit boards as well as multi-layer boards. Here comes the details for your reference.

• For FR-4: Sheng Yi, King Board, Nan Ya, Polycard, ITEQ, ISOLA

• For CEM-1 & CEM 3: Sheng Yi, King Board

• For High Frequency : Sheng Yi

• For UV Cure: Tamura, Chang Xing ( * Available colour : Green) Solder for Single Side

• For Liquid Photo: Tao Yang, Resist (Wet Film)

• Chuan Yu ( * Available colors: White, Imaginable Solder Yellow, Purple, Red, Blue, Green, Black)
