PAGE 1 Product Quality & Reliability Drop, Tumble Seal & Accelerated Failure Mode (AFM) MC95 Andrew Biondo Director Quality Engineering
PAGE 2 Product Qualification testing Key product Qualification tests performed for acceptance Functional verification (display, scanner, battery, Keyboard, WLAN radio, scanner interface) Thermal Shock (MIL-STD 810 F method 503 standard profile -40 - +70 C rapid transition) Vibration (MIL-STD 810 F method 514 procedure I, 1 hr per axis, 3 axis) Operational Temperature Cycling (MIL-STD 810 F method 520.2 industrial, -20C to +50C) ESD (EN61000-4-2) 8KV/15kV LOW temp storage (MIL STD 810F Methods 502.4) HIGH temp storage (MIL STD 810F Methods 501.4) Cargo packaged drop (ASTM D775-80 & MIL STD 810F Method 514,Procedure II) Cargo unpackaged drop (ASTM D775-80 & MIL STD 810F Method 514,Procedure II) Drop shock testing (MIL STD 810F= Method 516.5, Procedure IV, 36 drop @ 48 ) Tumble (EN60069-2-31 formerly IEC 68-2-32, 1 meter or ½ meter) Electrical EMC compliance (EN61000-4-3, 4-4, 4-5, 4-6, 4-8, 4-11) EN60529 Dust seal IP6X EN60529 Water ingress IPX7 Battery drops testing over operating temperature 2
PAGE 3 IPX7 per EN60529 Water exposure to verify seal integrity of the enclosure Immersion, 1 meter water, 30 minutes 1 meter immersion tank (product test)Vacuum testing (product & component test) Vacuum testing performed on: Monocoque enclosure End cap assembly Keypad assembly Final assembly MC95XX 3
PAGE 4 IP6X per EN60529 Dust exposure to verify seal integrity of the enclosure Tested with enclosure under vacuum for 8 hrs Before test photoAfter test photo 4
PAGE 5 Vibration Per MIL-STD-810, Method 514 Verify mechanical and assembly integrity 0.04g 2 /Hz Random (20Hz to 2KHz) 1 hr each of three (3) axis Multiple axis vibration 5
PAGE 6 1 meter tumble2000 cycles (4000 impacts) Tumble Per EN60068-2-31 Verify mechanical durability and assembly integrity 1 Meter tumble, 2000 cycles (4000 drops) 6
Drop testing can is done per Motorola method & MIL-STD-810F method 516.5 What is important to know…. –Each product may or may not meet certain aspects of the Mil-Std-810F test method…The MIL-STD methods does not specify pass fail criteria…. –Drop Considerations…3 samples dropped in each case. Moto MC95MIL-STD-810F tm 516.5 Is the unit on?Unit operating Unit not operating, loss of data is allowed Is the surface concrete?Concrete* 2 Plywood over concrete Over temperature range?Cold, room, hot 25C only Number of drops?36 drops/sample 26 drops total for all samples Corners,edge & surface Advantage Motorola performs drop testing to not one but BOTH methods shown above Deep Dive on drop testing
9:36:55 AM 8 Drop Slide Test performed in proprietary AFM testing Accelerated Failure Mode (AFM) is reliability testing beyond spec. Real life accidentally drop of product, on Concrete Parameters: Height:4' Drop Distance:6' Slide Distance:1-1.5' Orientation # 1:Top Face + Up, Down, Left, Right Orientation # 2:Bottom Face + Up, Down, Left, Right Drops per cycle:8 Temperature:+25°c, +50°c, -20°c Drop testing (Continued) 1-1.5' Drop Slide Test Wall 4' 6'
