WRIST
BAND
Description
Conductive wrist band prevents build-up of excessive static
charges generated by Ungrounded peronnel to ensure maximum
protection to sensitive components
Wrist Band
Regardless of wrist size, "one size fits all" Wristat is fully
adjustable and is available in the following styles :
|
|
|
* Elastic band
* Velcro band
* Metal band
|
 |
The
permanent conductive properties of all the 3 styles of wrist
band ensure reliable, rapid and continuous draining of static
charges. To ensure the safety of the user, the design of the
Wristat® is such that There are no exposed conductors. Another
common feature is the Special "flexi-hinge" which allows a close
, comfortable fit whereby the Strap wraps snugly around the
contours of the user's wrist. All the 3 styles of wrist band
are cleanroom compatible.
WIS-06 CORDLESS ANTI-STATIC WRIST STRAT
FUNCTION TEST & ANALYSIS REPORT
1).FUNCTION TEST COMPARISON
(A). Ordingary anti-static wrist strap w/ground wire (TYPE A)against
the cordless anti-static wrist strap (TYPE B)comparison. |
TEST METHOD FOR WIS-06 ANTI TATIC CORDLESS WRIST STRAP |
1)
Area range factor-(TYPE A )gives end-users limited area due
to length of ground wire &connecting Point. (TYPE B)give end
users unlimited area for free movement .makes supervision works
easier with lesser time and wider scope.
2) Reliability-(TYPE A ) endusers must from time to select &check
good connection point groundE (TYPB) do not require this procedure.
3) Function checking method TYPE A) must use special instrument
& need to check ground cord connection constantly for good dissipating
function. (TYPE-B)only need to use multimeter to check dissipating
function. |
INSTRUMENT
A. ANY MULTIMETER
Step 1.touch A & B part (+,-) : 106
ohms < R<107 ohms if the over
107 ,them try to tighten screw
until within range. Step 1. |
Touch
A & C part (+, -) : 106 ohms
< 107 ohms if the over 107
,then change the strap.
B. WRIST STRAP METER
Touch part A by the ground cord: 106ohms<107
ohms the same result as method A.
2). PERFORMANCE ANALYSIS
(TYPE A ) ANTI-STATIC WRIST STRAP W/GROUND WIRE (EXCELLENT GROUNDING
SITUATION) (TYPE B ) ANTI-STATIC CORDLESS WRIST STRAP

PRINCLPLE APPLICATION
As per physical principle of " corona" discharge effects and
point discharge, by transmission of electric potential difference
to arrive the effect of electrostatic elimination.
