This detail documents a generic view of the vertical design intent: the layer count, the thickness of the copper layers, the dielectric materials in between, and the presumed thickness and dielectric properties of the solder mask
material covering the outer-layer surface copper (FIGURE 2).
If the problem is a short, it may be plainly visible on the full-color LCD screen as a burned spot that is discolored brown, instead of the normal green solder mask
of the PCB.
Green identifies the solder mask
at the substrate level, but in three regions the surface of the solder mask
is represented by colors (blue, magenta, white) that indicate a higher elevation.
Unimicron Germany is in the process of rebuilding its inner layer fab as a completely automated Industry 4.0, state-of-the-art facility, and upgrading its Outerlayer and Solder Mask
capacity and capabilities.
Under the framework, Sun will develop liquid solder mask
ink to be used in Camtek's inkjet system for PCB (Printed Circuit Boards) applications.
The multi-wavelength feature, in maskless lithography for manufacturing printed circuit boards, supports many photoresists, ranging from general-purpose dry film to conventional solder mask
. For prepress operations in the printing industry, computer-to-plate (CtP) systems with UV-LED can support highly cost-efficient, mature UV-plate technology.
I normally take a few cracks at solder mask
as it is an easy target and continues to be my greatest challenge.
Co., Ltd., Taiyo America initially imported Taiyo's liquid photoimageable (LPI) dielectric coatings (solder mask
) and conductive products.
You get a solder mask
on both sides, silk screen (legend), and a 6/6 process.
In a recent interview with Circuits Assembly, longtime task group chair Dave Vaughan, marketing manager, Taiyo America, noted that revision D began simultaneously with the Solder Mask
Shipleys new |Aegis' solder mask
also allows high resolution so that narrow |solder dams' are possible between surface mount pads.
