Product Details

Fr4 HDI Kid Toys Double Layers PCB is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on.

High Density Interconnects (HDI) board are defined as a board (PCB) with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces (<100 µm), smaller vias (<150 µm) and capture pads (<400 µm), I/O>300, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology. HDI board is used to reduce size and weight, as well as to enhance electrical performance.


If divide the board according to manufacturing technology, major based on hole diamter size, it'll divid into two types:

Normal through hole (diameter >=0.20mm (8mil)
HDI (diameter <=0.15mm (6mil)
According to copper thickness, it can be divided into

Normall copper: copper thickness: 0.5 OZ, 1.0 OZ, 2.0 OZ,
Heavy copper: copper thickness: >= 3 OZ
According to core material, it can be divided into

Rigid FR4 PCB: Only FR4, it is rigid for whole board;
Rigid-flex circuits: Rigid FR4 plus flexible circuits;
According to Tg value of FR4, it can be divided into

Normal Tg: Value 130, 135, 140;
High Tg: Value 170, 180;
According to radio frequency (RF) level of PCB, it can be divided into

Normal: < 300 Mhz
High Radio Frequency: 300MHz ~ 3GHz,or even bigger
According to board thickness, it can be divided into

Normal: >=0.30mm
Extra Thin: 0.10~0.30mm;
