ANSI/EIA-960-A Page 1 ASSEMBLY COMPONENT TRAY - ACT 1 Scope This standard

12、covers requirements for Assembly Component Trays ACTs used during automated assembly processes. The standard size is covered which works with tray slots handling an envelope of 298.45mm (11.75inches) x 254mm (10inches) and the “J” size which works with tray slots handling an envelope of 322.58mm (12

13、.7 inches) x 135.89mm (5.35 inches). 2 Introduction This standard was formulated to provide dimensions and tolerances necessary for trays to locate components in matrix positions for existing automated handling equipment. The standard ACT tray will fit within the footprint of two side by side JEDEC-

14、PGA Package trays which measure 322.58mm x 135.89mm (12.7” x 5.35”) each. They can also be used as shipment packages in the logistic chain, where the tray box both RSC (Regular Slotted Carton) style and self-locking optimize the space used on a US 48” pallet and the A2N and L9N air cargo containers.

15、 Both RSC and self-locking boxes designed around the ACT dimensions maximize parts within the 1728 in3 shipping volume limit without incurring Dimension Weight charges. The “J” ACT tray matches the outside dimensions and general geometry of PGA Package trays. It is designed as a form, fit, and funct

16、ion, alternative to JEDEC-PGA trays. 3 Applicable Documents Unless otherwise specified the following documents form a part of this standard to the extent specified herein: EIA-383 “Preparation for the Delivery of Electrical and Electronic Components” ANSI/ESD S541 “ESD Association Standard for the P

17、rotection of Electrostatic Discharge Susceptible Items” EIA-556 “Electronic Industries Association Outer Shipping Container Bar Code Label Standard” EIA-583 “Packaging Material Standards for Moisture Sensitive Items” EIA-624 “Product Package Bar Code Label Standard for Non-Retail Applications” 4 Req

18、uirements 4.1 Assembly Component Trays (ACTs) must meet the requirements defined in the Figures and Tables presented herein. 4.2 The packaging, materials and processes shall not adversely affect the mechanical and electrical characteristics or marking of the components. For intermediate and final pa

19、ckaging, refer to EIA-383 “Preparation for the Delivery of Electrical and Electronic Components,” ANSI/ESD S541 “ ESD Association Standard for the Protection of Electrostatic Discharge Susceptible Items,” and EIA-624 “Product Package Bar Code Label Standard for Non-Retail Applications.“ ANSI/EIA-960

A 3.81 .150 minimum flange is to remain around outside bottom of tray as an area for vacuum cup attachment. ANSI/EIA-960-A

21、 Page 3 Figure 2 Orientation Proof Tray Feature Locations Note: 1.) R 6.50 .256 cuts can be used for tray stack guide rods that are 12.7 .5 in diameter. 4.4 Each tray in a stack shall have the same orientation as the one below it. All orientation features will align. The tray should have eight side

22、stacking lugs with lateral retention lugs to make the stack stable. The locations of the stacking supports ANSI/EIA-960-A Page 4 must be within the stated areas shown in Figure 3&4. See Figures 4-5 for details of stack supports. FIGURE 3 3D STACK VIEW NOTE: Orientation notches and pin boss features

23、should align. All trays in a stack should align so there is no 180 degree rotation requirement. FIGURE 4 TRAY STACK DETAILS ANSI/EIA-960-A Page 5 4.5 Trays shall be designed and made so that they can be stacked without being stuck together or breaking. The maximum lateral movement of one tray stacke

24、d on another is .254 .010 (Figure 5). FIGURE 5-DETAIL B STACK LUG DETAIL NOTES: 1.) A minimum stack clearance is necessary for automated tray stack separators. 2.) Trays should not adhere to each other in the stack. 3.) Accumulative lateral movement should not exceed 3.18 .125 for the top tray on a

25、tray stack of 12 trays. 4.6 A maximum clearance of .508 .020 should be left between the tray above and the part beneath, when the trays are stacked (Figure 6). Excessive clearance creates opportunities for parts to float out of pockets during shipping. FIGURE 6-DETAIL C PART TRAY CLEARANCE ANSI/EIA-

26、960-A Page 6 4.7 “J” Tray Dimensions FIGURE 7: “J” TRAY DIMENSIONS 4.8 The tray shall withstand, without any adverse effects, a wide range of temperatures during transit and storage. The tray shall also be within stated dimensional tolerances inside the range of acting temperatures: Acting temperatu

27、re min. +18 C (64.4F) max. +38 C (100F) Relative Humidity min. 10% max. 90% Transit and storage temperature min. -40 C (-104F) max. +65 C (150F) ANSI/EIA-960-A Page 7 0.5 mm maximum0.5 mm maximumActing temperature is the temperature at which the tray is expected to be used or measured. The tray shou

28、ld be stabilized at least 24 hours in this temperature range prior to use or measurement. Transit and storage temperature range is the temperature span that the tray must endure, but during which time the dimensional tolerances are not required to be met. 4.9 Components shall remain in known positio

29、ns in the tray during all handling operations. Components must also remain in known positions when the tray is tilted up to a fixed position of 45 degrees from horizontal. 4.10 Trays shall be suitable to withstand storage of the components without danger of migration of contaminants onto the surface

30、s, or the emission of vapors which would make soldering difficult or deteriorate the component properties or terminations by chemical action. 4.11 A stack of trays should be covered by an empty tray or lid/cover to protect components. 4.12 Component fit and movement in the tray cavities are subject

31、to the following requirements: a) Component rotation is limited to 10 maximum. b) Lateral movement of the component shall be restricted to 0.5 mm maximum (Figure 7). c) Components shall be removable from the cavity in a vertical direction without mechanical restriction. Figure 8 - Maximum lateral co

32、mponent movement 4.13 Component placement locations in the tray shall be referenced from the centerlines of the useable area of the tray with a non-accumulative tolerance in the x and y direction of the matrix. 4.14 Bar code labeling (if required) shall be visible during normal operation. 4.15 Trays

33、 should be recyclable and permanently marked with visible recycling symbology. ANSI/EIA-960-A Page 8 ANNEX A INFORMATIVE APPLICATION NOTES: A1 For applications where manual loading or unloading of trays is required, a finger trough of 12.7 .500 is suggested. FIGURE A1 FINGER PICK TROUGH A2 For visio

34、n applications where zero obstruction of the part leads is necessary, a minimum 3.81 .150 by 3.81 .150 by 3.81 .150 gripper pick area should remain clear around the top ends of the part in the tray pocket. FIGURE A2a GRIPPER CLEARANCE ANSI/EIA-960-A Page 9 FIGURE A2b GRIPPER CLEARANCE A3 Some placem

35、ent equipment will require a minimum 20.32 .800 x 20.32 .800 square area be left open in the center of tray for tray vacuum lift devices. It is suggested that this be left open where possible, and that the designer utilize even column quantities to ensure this area is left open. A4 Where parts have

36、defining geometry for symmetry, pocket designs should include orientation proof features. Where parts have no defining geometry for symmetry, the part location indicator should be used as a reference for orientation of parts in pockets. See Figure A5.
