PBT-531 Shielded Bag Test Kit

I. IntroducƟon

The Prostat PBT-531 is a mul-purpose portable tool that has a variety of uses:

• When used with the supplied PBF-520 Shielding Bag Test Fixture, a storage oscilloscope and a

computer the system can be used to test the discharge shielding properes of packaging materi-

als based on ANSI/ESD STM 11.31.

• The PDS-510 Discharge Simulator can perform two pin manual HBM tesng on ESD sensive

devices up to 4,000 volts. (See ANSI/ESDA/JEDEC JS-001 – Human Body Model Tesng).

• The PDS-510 comes with a precision DC power supply that can be used to charge conducve and

dissipave materials.

WARNING

As with any electrical device, use proper electrical precauons to avoid personnel shock.

Operang discharge simulators such as the PDS-510 HBM Discharge Simulator can result in

electromagnec interference (EMI). Individuals equipped with a heart pacemaker must not

operate the instrument or be in the vicinity while it is being used.

WARNING

Do not operate the PDS-510 with the cover removed. Internal voltages as high as 4,000 volts

are present when powered on. This could present a shock hazard to personnel.

WARNING

This equipment must not be operated in any environment where ﬂammable gases or fumes

are present as this represents a safety hazard.

SERVICE

Do not aempt to service this PDS-510 yourself. Opening the covers of the unit may expose

you to high voltages and possible electric shock. If the unit requires service contact Prostat

for assistance. Opening the cover without authorizaon will void the warranty.

II. Components Included with the PBT-531

• PDS-510 HBM Discharge Simulator

• PBF-520 Shielded Bag Fixture

IV. Pre-Test Setup

A. Aach the supplied red test lead from the PDS-510’s red HBM Output to the red connector on the

Discharge Arm (C) of the PBF-520 ﬁxture. (Figures 1 and 2).

B. Aach the supplied (short) green lead to the ground connector on the PDS-510 and the other end

to the ground connecon point on the Base Assembly (A) of the PBF-520 ﬁxture.

Figure 1: Connect the short red lead to the HBM

Output connector on the PDS-510

Figure 2: Connect the other end of the red lead to

the Discharge Arm. Connect the short green lead

to the base assembly.

C. Aach a second (long) ground lead from the open PDS-510 ground connector to a known AC

ground using the Q007B Grounding Cube (Figures 3 and 4).

Figure 3: Connect the long green lead from the Figure 4: Connect the other end of the long green

ground lead to the Q007B of an outlet.

D. Connect the current probe coming from the Capacive Arm to the male end of the 50-ohm termi-

nator (Figure 5).

E. Connect the female end of the 50-ohm terminator to Channel A of the PicoScope (Figure 6).

F. Connect the supplied USB cable from the PicoScope unit to a computer.

current probe.

terminator to Channel A of the PicoScope.

V. System VeriﬁcaƟon Test

A. Install the PicoScope soware onto the computer by downloading it from Pico’s website at hps://

www.picotech.com/downloads. Use the version that is closest to the model of your Pico Scope.

B. Insert the supplied USB Thumb Drive and copy the 3 ﬁles named “Waveform Veriﬁcaon Setup“,

“Shielding Bag Test File” and “Shielding Bag Test File with Manual Cursors” to your computer’s

desktop.

C. Launch the PicoScope soware. Note: It is recommended that you launch the Pico soware ﬁrst

and then open the ﬁles from the thumb drive.

D. From the PicoScope soware, click on File > Open and select the “Waveform Veriﬁcaon Setup

ﬁle” from the desktop

E. Turn on the PDS-510 by sliding the Main Power switch to the ON posion on the side of the meter.

F. Switch the POWER to the ON posion.

G. Switch the RANGE to the HIGH posion.

H. Switch the HIGH VOLTAGE to the ON posion.

I. By using the knob, adjust the voltage to 1.00 (1,000 volts).

J. In the PicoScope soware, if needed, move the yellow trigger icon above the scope’s zero line

(0.2A) on the levercal scale (Figure 7).

K. Ensure that the scope horizontal scale is set to 100 ns per division (Figure 7).

L. Without inserng a shielded bag onto the ﬁxture, set the Discharge Arm onto the Capacive Arm.

Set the 5 lbs Electrode on top of the Discharge Arm.

M. Click the “Stopped” buon at the boom lehand poron of the screen to place the scope in “ac-

quision” mode. The wording “Stopped” will change to “Running” (Figure 7).

N. Iniate a discharge by pressing the red DISCHARGE buon on the PDS-510. If a waveform is ac-

quired, the “Running” will change to “Stopped”.

O. Using the computer mouse drag the lescope cursor (vercal doed line) to the leof the dis-

charge waveform start and the right cursor to the point where the waveform decays to zero. The

calculated energy should be 50 ± 6 uJ (microjoules) and the peak current should be greater than 420

mA (milliamps 0.42 amps). The blue line is the discharge waveform and the red line is the calculated

energy curve in microjoules (Figure 8).

If the energy and/or the peak voltage are less than required, increase the voltage unl the required peak

voltage and energy levels are obtained. This voltage level might be in the 1030-1060 volt range.

Note: It is recommended that the discharge voltage be adjusted so that the energy is 50 ± 2 uJ. If there are

no values displayed in the red circle area move the right cursor slightly and the values should appear.

VI. Shielding Bag TesƟng

The following test sequence describes the basic procedure as outlined in ANSI/ESD STM 11.31. The test is

designed for 20x25 cm (8x10 inch) stac shielding bags.

A. From the PicoScope soware, click on File > Open and select the “Shielding Bag Test File” or

“Shielding Bag Test File with Manual Cursors” ﬁle from the desktop.

NOTE

If you wish the soware to analyze the test automacally, use the “Shielding Bag Test

File”. If you wish to analyze the data manually, select the “Shielding Bag Test File with

Manual Cursors”.

B. Lithe Discharge Arm (C) and place it into the notch of the Bracket (E) (Figure 9).

C. Open the shielding bag to be tested and insert the Capacive Arm (D) into the bag (Figure 10).

Place the bag so the top of it lines up with the mark on the Capacive Arm (Figure 11).

Figure 10: The CapaciƟve Arm inside the shielded

bag.

Figure 11: The end mark on the CapaciƟve Arm

represents 10 cm (4”) from the top of the shielded

bag.

D. Move the Discharge Arm so that it contacts the top of surface of the bag.

NOTE

It is important that the Discharge Arm is properly aligned in the bracket notches.
