Advantages
a) FR-4 Immersion gold PCB. It’s suitable for handheld and consumer applications. It’s also Lead free compatible.
b) RoHS compliant and suitable for thermal reliability needs,and Lead free assemblies with a maximum reflow temperature of 260.
c) ISO certified PCB manufacturing factory.
d) PCB manufacturing on required specifications. Right manufacturing instruction (MI), comprehensive equipment management and maintenance and process control, strict WIP inspection and monitoring as well as working instruction, all those make the whole fabrication process totally controlled.
e) Meeting your printed circuit board needs from PCB prototyping to mass volume production.

PCB knowledge: The components of multilayer PCB --- thin laminates
A multilayer board consists of copper foils, thin rigid laminates and prepreg sheets.
Thin laminates are used for inner cores and are available in so many different thicknesses that almost any specified build-up can be accomplished.
Different thickness of thin laminates
| mm | mils | | mm | mils |
| 0.050 | 2 | 0.360 | 14 |
| 0.075 | 3 | 0.410 | 16 |
| 0.100 | 4 | 0.460 | 18 |
| 0.125 | 5 | 0.510 | 20 |
| 0.150 | 6 | 0.560 | 22 |
| 0.175 | 7 | 0.610 | 24 |
| 0.200 | 8 | 0.660 | 26 |
| 0.250 | 10 | 0.710 | 28 |
| 0.300 | 12 | 0.760 | 30 |
The thicknesses are valid for the bare laminate, with the copper foil being excluded. We can see the cores are quite thin. For a total thickness of 1.6mm (0.063inch) board, the more layers, the thinner the laminates should be. See our reference Multilayer PCB stackup for 0.063inch thick.

FAQ
Do you sell via in pad PCB?
Yes. Via in pad (VIP) is a good real estate saving. We offer this kind of PCB for many applications like microcontroller, GPRS etc.
