9.BGA:Ball Grid Array(BGA 球栅列阵),是一种封装形式,其输入输出点是在元件底面上按栅格样式排列的锡球。 10.Blind via(盲孔):是 PCB 的外层与内层之间的导电连接,但不会通到板的另一面。Buried via(埋孔):则是 PCB 的两个或多个内层之间的导电连接,从外层无法看见。 11.Posive Pattern:正像图形,也...

Tab Routing Vs V Groove PCB Panels Making a choice if you should use tab routing or v groove methods in the panel largely depends on your PCB design. These are some factors to consider before you make a decision. Edge components It is possible that your breakaway tab PCB relies on compone...
A PCB manufacturing process by combining different boards into one panel to increase the manufacturing efficiency. Pattern Plating Selective plating of a conductive pattern. Peelable Solder Mask A layer ofsolder maskthat can be peeled OFF from the board. ...
Featuring a precision dual optical configuration with an expertly curated array combination, our system ensures the light source maintains a parallel angle of less than 5 degrees,º The UVLED light source activates automatically only when the substrate is being exposed, eliminating any standby power...
The length and width of the PCB panel should be as close as possible, so it is common for PCB panelization in the array of 2x2, 3x3, etc.Edge rails are usually added to the PCB panel, and there are 4 NPTH (non-plated through-hole), each with an aperture of 4mm....
· The energy attenuation of UVLED light source within 30 thousand hours is about 1%, which effectively improves the stability of exposure quality. Product Parameters Led exposure machine Expose Size: 900mm×650mm panel kness 0.01mm~4.5mm light source UVLED Parallel angle <...
