    14、3.1-2015.) FOREWORD Electrical overstress (EOS) and electrostatic discharge (ESD) can damage or degrade certain electronic components and assemblies. The intent of this standard is to provide test requirements for soldering/desoldering hand tools used in ESD Safe work areas or on materials that are

    15、deemed to be ESD sensitive. The methods described herein can be used during procurement, qualification and verification of soldering/desoldering hand tools to verify that electrical integrity has not been compromised that could result in EOS/ESD damage. There has been no attempt to define how the so

    16、ldering irons are to be used. This standard1 was originally approved on May 21, 2000 and was designated ESD STM13.1-2000. ANSI/ESD S13.1-2015 is a revision and redesignation of ESD STM13.1-2000 and was approved on June 23, 2015. At the time ANSI/ESD S13.1-2015 was prepared, the 13.0 Hand Tools Subco

    18、 equipment base. If soldering systems with oscillator or microprocessor frequencies higher than 20 MHz are to be qualified, then wider band width measuring equipment should be considered. Failure to do so is likely to qualify equipment that might otherwise be disqualified.” 6.1 Soldering/Desoldering

(SEE FIGURE 2.) 6.1.2 Hot Soldering Iron Tip Method 1 The determination of tip-to-ground resistance is accomplished by using a current source and a millivoltmeter to measure the resistance betw

    21、een the soldering tip and the equipment grounding prong (green or green with a yellow stripe wire) of the AC power cords plug. 6.1.2.1 Test Apparatus 6.1.2.1.1 Test Electrode The test electrode shall be single-sided or double-sided printed copper clad circuit board material (commonly referred to as

    22、2 oz. copper clad), or solid copper, 1.6 mm (0.062 inch) thick, or equivalent. Tin the electrode prior to use. To tin the electrode, apply a small amount of solder to a small area near the end of the electrode that will be used as the point of contact for measurements (see Figure 1). NOTE: The elect

    23、rode is designed to be able to sustain heat incurred while being wet with solder from the hot soldering iron tip of the unit under test. This electrode is designed to be replaceable since it will deteriorate after repeated testing. The length of interconnecting wires should be kept as short as possi

    24、ble to ensure the highest accuracy in test results.

    28、 be capable of measuring zero to 20 milliamperes with a resolution of 0.1 milliamperes, and an accuracy of 1%. 6.1.2.1.6 Ohmmeter The ohmmeter shall be capable of measuring zero to 100 ohms with a resolution of 10 milliohms, and an accuracy of 1%. The ohmmeter should have a set of sharp pointed lead

    29、s that accepts alligator clips. Make sure the meter lead resistance is zeroed out before making measurements. 6.1.2.2 HAZARD WARNING: IT IS NOT REQUIRED TO DISCONNECT THE GROUNDING CONDUCTOR OF THE UNIT UNDER TEST. BREAKING THE CONNECTION TO GROUND MAY CAUSE AN ELECTRIC SHOCK HAZARD. CAUTION: THE FO

    30、LLOWING PROCEDURE INVOLVES WORKING WITH ITEMS (HEATER, IRON TIP, AND TEST ELECTRODE) HAVING HOT SURFACES. 6.1.2.3 Resistance Measurement Procedure 6.1.2.3.1 The test apparatus is checked by separately placing two resistive elements, (a shorting wire 0.1 ohms and a 2.0 ohm + 1% resistor) across the t

    31、est apparatus electrodes. These resistance measurements shall be within 4%. 6.1.2.3.2 Connect the test apparatus as illustrated in Figures 2 and 3. The test apparatus negative electrode shall make an electrical connection to the ground reference point of the unit under test. The unit under test shal

    32、l be turned on and adjusted (if applicable) to achieve normal operating temperature. ANSI/ESD S13.1-2015 5 6.1.2.3.3 Clean the tip by wiping on a wet sponge. Touch the HOT soldering iron tip of the unit under test to the tinned area of the test electrode. Apply solder to form a good electrical conta

    33、ct. Wait for the measurement to stabilize, typically less than 5 seconds. 6.1.2.3.4 Calculate and record the measurement - each 1 millivolt on the millivoltmeter equals 0.1 ohms. (Example: a read-out of 10 millivolt DC indicates 1.0 ohms.) 6.1.2.3.5 The results shall be equal to or less than 2.0 ohm

    34、s (see Section 8.0). 6.1.3 Cold Soldering Iron Tip Method 2 The tip-to-ground resistance is measured by using an ohmmeter to check the resistance between the soldering tip and the safety grounding prong (green or green with a yellow stripe wire) of the AC power cords plug. (See Figure 5.) NOTE: Whil

    35、e cold testing is acceptable, hot testing is preferred. Also, low output voltages ( 1.0 volt) on some ohmmeters, especially digital meters, may result in a higher measurement because of contact resistance due to oxides on surfaces.
