Aluminum PCB Capability

Specifications

Category	Capability	Details
PCB Material Brand	Goldenmax GL11, Guangzhou Aluminum	(Goldenmax GL11, Guangzhou Aluminum)
SolderMask	LB Brand	LB-1900W
Copper Thickness	18um/25um/35um/70um（0.5oz/0.75oz/1oz/2oz）	Refers to the thickness of finished PCB outer copper，0.5oz=18um，1oz＝35um
PCB Thickness	0.8-2.0mm	0.8/1.0/1.2/1.6/2.0 mm
Thickness Tolerance( thickness≥1.0mm)	± 10%	Thickness measurement position is the thickest position of the whole PCB (including copper + Soldermask + Silkscreen)
PCB Thickness Tolerance (Thickness <1.0mm)	±0.1mm	Thickness measurement position is the thickest position of the whole PCB (including copper + Soldermask + Silkscreen)
Minimum Trace Width	± 10%	At present,we can process min 8mil trace width,and ≥10mil is advised
Minimum Trace Distance	8mil（0.2mm）	At present,we can process min 8mil trace distance,and ≥10mil is advised
Drilling Aperture	Hole size≥ PCB thickness ≥1.0mm	The minimum hole shall not be less than the thickness of the PCB, and it shall not be less than 1.0mm
Drilling Hole Tolerance	±0.1mm	Hole tolerance is ±0.1mm, for example, designed for 1.5mm hole, the drilling hole of the final PCB in 1.4-1.6mm is normal.
Soldermask Type	Photosensitive ink	Photosensitive ink is now the most used type, thermosetting oil is generally used in low-grade light panels
Soldermask Bridge	0.15mm	If the soldmask color is green or blue, the pad spacing must be bigger than or equal to 8mil; White and black ink pad spacing ≥10mil
Minimum Silkscreen Width	≥0.15mm	Minimum width of characters is 0.15mm, if less than 0.15mm, the physical board may cause unclear characters due to design reasons.
Minimum Silkscreen Height	≥1.0mm	Minimum height of characters is 0.8mm. If the height is less than 0.8mm, the characters may be unclear due to design reasons
Max Size	Standard：480x580mm Max：580x1180mm	The limit size is the maximum size that can be machined, but the cost will increase due to plate waste and high processing costs
Dimension Accuracy	±0.15mm	CNC contour tolerance is ±0.15mm, V-Cut contour tolerance is ±0.15mm, mold shaping contour tolerance is ±0.1mm
Panel: no gap between the panel	0mm	The gap between the PCBs is 0mm
Panel: there are gaps between the panel	2.0mm	If you want space between each PCB while panelling, the distance should be bigger than 2.0mm.
