|
| Extensive
use of highly electro-static discharge (ESD) sensitive components |
|
| in today's electronic industry necessitate manufacturing & assembly shop | |
| floors
to be designed and set up with this aspect in mind, and it is necessary |
|
| that
the equipment used there must confirm to this requirement. We have done |
|
| considerable
research in order to provide this solution in regard to Magnifiers. |
|
| The
damage to the sensitive components occurs due to electric discharge |
|
| between
component and some charged object in the vicinity, or a conductor |
|
| shorted
to the ground. The damage can be total or irreversible, and if the |
|
| component
is mounted on a board the entire board can get rejected. Like all |
|
| other equipments and instruments used in these factories, the Magnifiers too | |
| have to be ESD proofed. In our ESD Safe Magnifiers this is ensured in terms of | |
| various parameters (quantitative values given below) such as static | |
| generation,
resistance value from surface to ground, and surface resistivity - |
|
| which must remain within the Dissipative Range. To attain these parameters | |
| we
use specially imported dissipative polymers, dissipative paints,
dissipative |
|
| coatings,
special electrical layout etc. |
|
| Electrical
Resistance Values of our Magnifiers & their components: |
|
| Surface
Resistivity
: 10E6 - 10E11 Ohms/sq |
|
| Surface
to Ground Resistance
:
10E5 - 10E9 Ohms |
|
| Static Generation (by friction with Thermo cool) : NIL | |
| The above figures confirm to requirement of EOS/ESD Association Standards | |
| 20.20
(1999) for Electrostatic Discharge control areas. |
|
| (NB:
It is necessary that all other items in the work area such as packing |
|
| materials/bags,
work bench surfaces, storage racks, grounding cords, chairs, |
|
| mats,
bins, floor surfaces, footwear/gloves/aprons, conveyor belts etc. have |
|
| resistance
properties that remain well within 10E3 to 10E12 Ohms.) |
