Fast HDI PCB prototype Manufacturing , small batch to production
HDI PCB – High Density Interconnect PCB
High Density Interconnects (HDI) are used to meet the market demand for complex designs in smaller form factors across the majority of market segments, (Wireless, Telecom, Military, Medical, Semiconductor, and Instrumentation).
HDI Circuit boards, one of the fastest growing technologies in PCBs, HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter.
They have finer lines and spaces always = <3mil They have a higher circuitry density than traditional circuit boards.
Andwin maintains years of experience with HDI products and was a pioneer of second generation microvias. now offer an entire family of microvia technology solutions for your next generation products.
Stack up of HDI PCB
Stack up of 1 Step HDI PCB
1 step HDI that need one lamination process,
the most like common PCB board,
after lamination ,laser drill out layer to sub out layer.
Stack up of 2 step HDI PCB
2 step HDI , it need twice lamination process with blind buried hole,
for example,a 6 Layers HDI PCB ,
first time, laminate L2 to L4 layer board ,
then laser drill L2-L3 or/and L4-L5,
and then finish other process.
Stack up of 3 steps HDI with blind via and buried via
3 or 4 step HDI process is similarly 1 or 2 steps ,
only differenci is that need more times lamination.
Anylayer connect of HDI printed circuit board
This type HDI design , need to adjust lamination stack up as normal symmetrical by our Engineer ,
but do not affect the orignal eletronical connect.
it is complex , depend on the orignal design of PCB.
