The calculated maximum aspect ratio (depth-to-diameter ratio) for via-hole filling without cavity creation by bias-sputtering, considering the shadowing effect, was found to be in good agreement with the experimental value, which was practically less than 1. The results indicated that reducing the...

1.A Rapid Hole Filling Algorithm for Arbitrary Shape;一种适用于任意形状区域的快速孔洞填充算法 2.Method of hole filling based on hole subdivision;基于孔洞分割的点云孔洞填充算法 3.A hole filling algorithm based on contours information is presented,and it conquers the limitation of the conventional ...
He's talking about a concave fillet on the top surface which means that the surfaces of solder in the middle of the via hole is lower than the surface of the board. That's my assumption. Phil Jim I'm kind of surprised, a little puzzled as to the problem he's actually having with...
It is very important to note that the smaller the via hole size, the better the result will be. Suggested is a via >=0.20mm. Via hole sizes less than 0.3mm have the best chance of getting filled, while between 0.3mm to 0.5mm sizes, filling results may vary. Because this is an unco...
The hole can be partially filled with an LPI solder mask or the filling can be washed off.Plugged vias are fully filled. Through-hole vias should be tented on both sides to reduce the chances of any chemical entrapment.The material for filling can be applied on a single side or both side...
A method of plating for filling via holes, in which each via hole is formed in an insulation layer covering a substrate so as to expose, at its bottom, part of a conductor layer located on the substrate. A copper film is formed on the top surface of the insulation layer covering the ...
PURPOSE: To eliminate continuity defects due to the shortage of filling in a viahole and defects at the time of forming a wiring pattern due to the extrusion of a via land, which were conventional problems in the printing process of a ceramic multi-layer board. ;CONSTITUTION: When a conduct...
The term via refers to a drilled hole that is copper-plated to create an electrical connection between two or more layers of a printed circuit board. Via filling is a PCB manufacturing technique in which the via hole is filled thereby completely closing the via hole using a conductive or non...
