ESD (Electrostatic Discharge) Test Access Control System
In today high end technology production environment, ESD (Electrostatic Discharge) has become one of the major stage need consider in the overall product quality control. In the traditional ESD testing method, it is very much depend on company management, production supervisor and individual employee responsibility to take care of the ESD issue. However, manual method cannot 100% control the ESD clearance of all employee, manually record on paper is easily prone to error and alteration, inefficient management or unreliable data source is difficult to be trusted or satisfied by the consignee, unable to satisfy the strict global standard such as when feet testing it will still allow even only one foot is pass, cannot issue different permission levels for special group of person (e.g. VIP, admin staff or handicapped employee).
With Bostex ESD Test Access Control System, it able to provide the following benefit:
1.Achieve stringent testing using card access and ESD level permission to prevent all illegal access or those that fail the ESD testing.
2.Automated strict ESD testing to enhance QC level
3.Low initial investment cost to achieve high QC standard
4.All electronic data are processed and manage by PC to free from human error and modification
5.Advanced electronic data management for accurate and efficient data to strictly control the protected area to reach the products ESD standard and gain customer trust
6.Able to test all the ESD criteria for every hand and feet to satisfy the global ESD standard
7.Able to grant the different ESD permission level such as hand only, feet only, none or partial testing according to the card ID with valid access
8.Working together with BTEPS module (over 20 over applications e.g. Physical Access Control, Time Attendance, Human Tacking, Visitor Management, Guard Tour, Payment, Car Park Management etc.), we are able to provide a complete one card integrated system to the customer.
Application Area
SMT production line, Clean room in various field such as Semiconductor Fab, High Tech R&D room, National defense or military ESD sensitive areas, Explosive processing areas, Maintain or Calibration areas for aero space industries, Pharmacy , Bio-chemical and hospital ESD restraint areas and every where the ESD control is required.
System Description
In many of the early days Electrostatic Protection Area, the electrostatic shoes, wristband are manually tested and recorded by supervised person which prone to mistakes and waste a lot of time/resource and cannot be easily audited
Bostex ESD Test Access Control System is managed by embedded controller and PC to make sure all the necessary person able to satisfy the ESD test criteria, record the access time and control by releasing the door lock/turnstile or activate alarm due to invalid access or ESD failure, therefore enhance the ESD testing efficiency.
1.It provides good management and control to prevent any chances of bypass the ESD testing or tailgating, i.e. one person tested and let multiple persons passing.
2.For strict access management, department or user group can be classified to undergo different test requirement. Such as office staffs read card for Time attendance recording only and the workers in the production line need to pass full ESD testing before granting access to the protected area.
3.The system able to process the verification and testing in real time, recording the event and send the information to PC for real time display and saving to database for auditing and reporting purpose.
4.For access controller with LCD display, it will provide a clear display on card error, time zones error, holiday access error or indicating light to highlight hand or feet ESD error and immediately prompt the employee of their current situation.
Specifications
1.The system is mainly consisted of:
a)ESD Tester (SURPA-6502)
i.Feet ESD Testing Resistance Range: High: R > 100MOhm; Pass: 750KOhm ≤ R ≤ 100MOhm; Low: R < 750KOhm
ii.Hand ESD Testing Resistance Range: High: R > 10MOhm; Pass: 750KOhm ≤R ≤ 10MOhm; Low: R < 750KOhm
iii.Tolerance: ±10%
b)ESD Interface board
c)ESD Access controller (BS800-ESD)
d)Door Controller (BSDC)
e)Wiegand Reader or Biometric
f)BTEPS Management Software.
g)Infra-red sensor
h)Exit push button
i)Door Electronic Lock or Tripod turnstile barrier
2.Beside the normal access control permission (location, time schedule, holiday etc.), the ESD control permission is making use of our system “Control Group” to fulfill different type of ESD testing criteria for different user. Currently up to 4 control group is defined:
a)Control Group #1: Access without ESD testing
b)Control Group #2: Access requires hand ESD testing
c)Control Group #3: Access requires feet ESD testing
d)Control Group #4: Access requires combination of hand and feet ESD testing. This group is further sub divided into:
i.Hand ESD testing before feet ESD testing
ii.Feet ESD testing before hand ESD testing
3.The controller will base on card ID and the respective control group to decide the ESD testing criteria before the release door lock/turnstile and at the same time generate ESD test record which include card ID, location, date & time, event (represent different ESD test result, up to 38 results).
4.All events will be display on BTEPS-MS (Monitoring Station) user interface in real time.
5.The controller could control the intelligent gating devices such as Turnstile, Swing gate or Flab gate. Also, it could control the general locks such as drop bolt, magnetic lock or strikes. The user could push the exiting button or read on the exiting reader for exit.
6.The ESD Test Access Control System can be integrated with Time attendance module (BTEPS-TC) to utilize the ESD access events to serve as Time attendance record and generating attendance management report.
