PCB Process Requirements

Project	Processing capacity	Process details
Number of layers	1~6 Layer	The number of layers refers to the number of electrical layers in the PCB (the number of copper layers). At present Jia Lixin only accept 1~6 layer board.
Plate type	FR-4 Plate	Plate type: Cardboard, half glass fiber, all glass fiber (FR-4), aluminum substrate, at present Jia Lixin only accept FR-4 plate. As shown on the right
Maximum size	40cm * 50cm	Gali Open material cutting work board size of 40cm * 50cm, usually allow the customer's PCB design size within 38cm * 38cm, the specific document audit shall prevail.
form factor Accuracy	±0.2mm	Board shape Tolerance ±0.2mm.
Plate Thickness Range	0.4~2.0mm	Gali Current Production Board thickness: 0.4/0.6/0.8/1.0/1.2/1.6/2.0 mm.
Plate thickness tolerance (t≥1.0mm)	±10%	such as plate thickness t=1.6mm, the physical plate thickness of 1.44mm (t-1.6x10%) ~1.76mm (t+1.6x10%).
Plate thickness tolerance (t<1.0mm)	±0.1mm	such as plate thickness t=0.8mm, the physical plate thickness of 0.7mm (T-0.1) ~0.9mm (t+0.1).
Min. line width	6mil	The line width is as large as 6mil and the minimum must be less than 6mil. As shown on the right
Minimum clearance	6mil	The gap should be as much as 6mil, minimum not less than 6mil. As shown on the right
Finished layer copper thickness	1oz~2oz (35um~70um)	The default conventional circuit board outer copper foil line thickness of 1oz, up to 2oz (need to order note description). As shown on the right
Inner layer copper thickness of finished product	0.5oz (17um)	The circuit board inner layer copper foil line thickness unification is 0.5oz. As shown on the right
Bore hole diameter (mechanical drill)	0.3~6.3mm	Minimum aperture 0.3mm, maximum aperture 6.3mm, if greater than 6.3mm plant to be treated separately. Mechanical drill bit specifications for the first order of 0.05mm, such as 0.3mm,0.35mm,0.4mm .... As shown on the right
Through hole single-sided solder ring	≥6mil	such as conductive hole or plug hole single-sided welding ring is too small, but there is enough space there is no limit to the size of the welding ring side, if there is not enough space and dense lines, the minimum single-sided solder ring must not be less than 6mil. As shown on the right
Bore diameter tolerances (machine drills)	±0.08mm	The bore tolerance is ±0.08mm, for example a hole designed for 0.6mm, and the finished aperture of the physical plate is allowed in 0.52--0.68mm.
Solder Solder Type	Photosensitive Ink	Photosensitive Ink is now the most used type, hot solid oil is generally used in low-grade single-sided cardboard. As shown on the right
Minimum character justifies	6mil	The minimum width of the character, if less than 6mil, the physical board may cause the character is not clear due to design reasons. As shown on the right
Minimum character eigenstates	≥1mm	The minimum height of the character, if less than 1mm, the physical board may cause the character is not clear because of the design reason. As shown on the right
Route and form Spacing	≥0.3mm	Gong Board shipments, line layer line distance from the board contour line is not less than 0.3mm;v cutting board shipments, the distance from the V-Cut center line can not be less than 0.4mm.
Puzzle: No Gap panel	0mm Gap Panel	The gap between the board and the board is 0mm. Click to view larger image
Panel: With Gap puzzle	2.0mm Gap Panel	Gap imposition of the gap should not be less than 2.0mm, or the side of the gongs more difficult. Click to view larger image
Pads Factory Copper Paving method	Hatch Way Copper laying	Manufacturers are the use of reduced copper (Hatch), pads software Design customers must be careful. As shown on the right
Picture slots in Pads software	With outline Line	If the plate on the non-metallic trough more, please use outline painting.
Window layer in PROTEL/DXP software	Solder Layer	A few engineers mistakenly put to the paste layer, Jia Lixin to paste layer is not to do processing.
Protel/ad Contour Layer	To use a keepout layer or a mechanical layer	Please note: A file allows only one form factor to exist, never allow two form factors at the same time, please remove the absence of the form layer, that is: drawing the shape of the keepout layer or mechanical layer can only be selected one. As shown on the right
Half hole process minimum aperture	0.6mm	Half-hole process is a special process, the minimum aperture must not be less than 0.6mm.
Solder Barrier Opening window	0.1mm	Solder resist is often said Green oil, Jia Lixin currently do not do solder bridge.
