Andrew LodgeWe just receive the machine and it is with nice packing ! It's really be worth this price .
Mareks AsarsMachine works well, Alex is the best salesman i ever met,thx for your support.
Adrian ShortThe JUKI feeders arrived yesterday and we inspected them through our Goods Receiving process. Our inspector was very excited and called me to see them

The Protel 99 SE provides 16 mechanical layers, which are used to set the dimensions,
data marks, alignment marks, assembly instructions and other mechanical information of
the board.This information may vary depending on the requirements of the design company
or PCB manufacturer.Can perform menu commands Design | MechanicalLayer circuit boards
set more mechanical layer.In addition, the mechanical layer can be attached to other
layers together with the output display.
Solder mask layer
Apply a coat of paint, such as antisolder paint, to all areas outside the pad to prevent
tin from being applied to these areas.The solder resistance layer is used to match pads
during the design process and is automatically generated.The Protel 99 SE provides two
Solder resistance layers: Top Solder and Bottom Solder.
Paste mask layer(SMD layer)
It acts in a similar way to the solder barrier, except for the corresponding surface -
bonded component pads during machine soldering.Protel99 SE provides Top Paste and Bottom
Paste protection layers.
It is mainly aimed at the SMD components on PCB board.If the board is full of DIP
(through-hole) components, there is no need to output Gerber files on this layer.Before
the SMD components are pasted on the PCB board, the solder Paste must be applied on each
SMD solder pad. In the steel mesh used for tin coating, the Paste Mask file must be used
to process the film.
The most important thing to be clear about the Gerber output of Paste Mask layer is that
this layer is mainly for SMD components. At the same time, compare this layer with the
Solder Mask introduced above to understand the different functions of the two layers,
because the two film pictures are very similar from the film pictures.
Keep out layer
Use to define areas on a board where components and wiring can be placed
efficiently.Draw a closed area on this layer as a valid area for cabling. Automatically
layout and cabling cannot be done outside this area.

The screen printing layer is mainly used to place printed information, such as the
outline and annotation of components, various annotation characters, etc.The Protel 99
SE provides Top Overlay and Bottom Overlay for screen printing.In general, all kinds of
annotation characters are in the top layer of screen printing, the bottom layer can be
The solder pads and through-holes on the circuit board need to penetrate the whole
circuit board to establish an electrical connection relationship with different
conductive graphic layers, so the system is specially set up an abstract layer -
multilayer.Generally, the pads and holes should be set on multiple layers. If this layer
is closed, the pads and holes will not be shown.
The borehole layer provides drilling information during the fabrication of the circuit
board (e.g. solder pads, which require drilling to pass through holes).The Protel 99 SE
provides two Drill beds, DrillGride and Drill Drawing.
