Power planes can be mapped out in the pre-layout stage, or completed PCB designs can be analyzed to pinpoint possible neck-down areas, such as the area shown in FIGURE 1.
More important, the heating effect of that plane shape neck-down is accurately characterized, and provides valuable information in driving a design change on the board.
The new technology has no neck-down
equipment from the process line, which allows for increased throughput.
The tubing neck-down
is performed in the same machine cycle as balloon formation, making it especially suitable for forming balloons from highly elastic and soft materials.
" symptoms such as lower respiratory congestion, hacking cough, chills, vomiting, and diarrhea are bright red flags indicating more discomfort and possibly some serious complications, and should be viewed as such.
The winder features a precise closed loop tension control system for materials that are sensitive to neck-down
strategy hinges on reducing the number of type model aircraft and procuring weapon systems that maximize commonality in support requirements.
Preforms are heated neck-down
and gripped positively by novel spring-loaded holding devices that expand outward against the inside wall of the preform neck.
transport of performs on mandrels is said to simplify handling and improve bottle quality by reducing scratches, deformation, and dust pick-up.
The specimen geometry was a micro die, with a neck-down
length of 20 mm and width of 3 mm, dimensions "L" and "W" respectively in ASTM D412.
With the Lump 2000 Series, this company is said to have made advancements for the detection of lumps and neck-downs
in two or three measuring planes.
* An optical system that measures diameter variations such as lumps and neck-downs
