12、 addition to two subparts of the ANSEIA 48 1 series (48 1-2 and 48 i-3), pertaining to a guideline for reel configuration and dimensions of reel diameters larger than 360mm (utilized in applications of 16mm to 56mm carrier taping) without necessitating the revision of these EIA Automated Component H
13、andling (ACH) publications at the present time. The editorial additions are divided into two sections containing advisory notes relative to widely used reel sizes and corresponding hub diameters. The first section (Page 2) covers 16mm and 24mm carrier tapes and is applicable to ELA-481-2. The second
14、 section (Page 3) covers 32mm, 44mm, and 56mm carrier tapes and is applicable to EIA-481-3. This guideline will not replace any information contained in ANSUETA-481-2 and 481-3 and is provided for guidance and clarification only. Note: It is the intent of the EIA ACH Committee that this guideline wi
15、ll be rescinded when all of the EIA ACH standards listed under Clause 3 below are revised. 3 Applicable documents This guideline is to be used in accordance with the following ELA ACH standards: a) ANSIEU-481-2, 16mm and 24mm Embossed Carrier Taping of Su#ace Mount Components for Automatic Handling
