case, the problem was exacerbat- ed by the bond breakers spray on their concrete slab. What AMC needed was a


free-floating floor that would meet the stringent ESD require-


at a rate of almost 1,000 ft2 per installer per day.


Not Just for SMT This past year, StaticWorx


was approached by FW Chase, a company that builds engineered environments and cleanrooms, to provide flooring for Macom, a semiconductor fabricator in Lowell, Massachusetts. Macom wanted to transform


its ISO Class-3 wafer fab facility into an ESD-protected environ- ment without shutting down the

ments in ANSI/ESD S20.20 while projecting their facility’s best-in-class appearance.


GroundLock Interlocking Tile GroundLock Extreme inter-


locking tile met all the require- ments. AMC appreciated the ruggedness of the tile, its chemi- cal resistance and visually appealing, low-maintenance sur- face, which never needs wax. Because the tiles interlock,


GroundLock installations re - quire no adhesive. This adhe- sive-free installation allowed AMC to maintain full operations throughout the project. Expan - sion, contraction and doming of tiles, due to minor shifts in sub- floor temperature, are the biggest obstacles to a perfect glue-free installation. With GroundLock, two layers


of fiberglass, sandwiched between the top and bottom layers of each tile, ensure dimensional stability. A completely automated manufac- turing pro cess —from the moment resins are extracted from rail cars all the way through packaging and palletization — guarantees precision interlocking and consis- tent tile thickness. These precision joints enable


workers of all skill levels to install GroundLock quickly, despite uneven subfloors, tight spaces or time constraints. The only neces- sary installation tools are a chalk line, dead-blow hammer and a bullet cutter. Many users install GroundLock tiles themselves, over surfaces ranging from old carpet to raised access panels to failing VCT and epoxy floors. Once placed, GroundLock


tiles can handle any level of traf- fic, including forklifts and scissor lifts. Heavy SMT lines are easily moved and relocated, and carts and trolleys roll as easily as they would over bare concrete. As GroundLock requires no adhe- sives, vapor permeation has no effect on the integrity of the installation. The installation crew at AMC installed about 30,000 ft2

A unique combination of five innovative features has been incorporated into Nikon Metrology’s new 225 kV microfocus X-ray CT (computed tomography) system, the XT H 225 ST 2x. As its suffix implies, it offers twice the data acquisition speed and doubles the filament lifetime, considerably extending the system uptime.


Doubling inspection productivity raises the system’s suitability for quality control (QC) applications on the shop floor, whether in vehicle component manufacture or any serial production environment. It heralds a major increase in factory efficiency by meeting the changing requirements of today’s manufacturing sector, whereby QC is starting to drive the operation and optimization of production lines, an ethos known as Quality 4.0.

the old floor, there was no visual telegraphing through the GroundLock tiles. Like AMC, Macom put GroundLock through a rigorous evaluation for compli- ance to ESD standard ANSI/ESD S20.20 as well as evaluating the tile for FOD generation, rugged- ness, flatness and appearance. Because of the tight space con-

straints in a cleanroom, the Chase installation team had to carefully coordinate the placement of tiles with ongoing cleanroom traffic. They were also required to


adhere to all the same cleanroom protocols as the Macom person- nel. The project was a complete success, with Macom deciding to duplicate the installation at another location. Contact: StaticWorx, Inc.,
