This standard replaces GB/T 16525-1996 "plastic leaded chip carrier package leadframe norms." This standard and GB/T 16525-1996 compared to the main changes are as follows. --- According to the standard range, the standard name of the original standard was revised to "a semiconductor integrated circuit plastic leaded chip carrier seal Lead frame mounted norms "; --- About Normative references. increase the introductory phrase; sampling standards set by GB/T 2828.1-2012 instead of SJ/Z9007-87; increase Plus references GB/T 2423.60-2008, SJ20129; --- 4.1 standard from "Design" to "lead frame size" and "coining depth" "insulating gap" and "horizontal spacing and lead Location (lead end portion) "of the contents was adjusted to 4.2; --- Of the standard "4.2 leadframe shape and position tolerances" in the corresponding provisions of the order have been adjusted, and added "chip bonding Subsidence area, "the relevant requirements; --- Revised standard for "scoliosis" requirements (see 4.2.1). the original standard specifies only (203.2 ± 50.8) mm nominal long strip on the side Bend should be less than 0.051mm, this standard over the entire length of the predetermined nominal; --- Revised standard on the "curl" requirements (see 4.2.2). the original standard specifies only texturized less than 0.51mm, this standard Carried out according to a predetermined thickness of the material, respectively; --- Revised standard on the "strip twisted" requirements (see 4.2.4). the original standard only provides a framework twist of not more than 0.51mm, This standard will be revised to frame twist twisted strips, and were based on a predetermined thickness of the material; --- Revised standard on the "twisted wire" requirements (see 4.2.5). the original standard specifies the lead angle and twisted lead width The maximum offset this standard removed the lead predetermined maximum width offset; --- Revised standard on the "depth coined" requirements (see 4.2.6). Standard on original coining coining width to depth is not considered, Jane Single predetermined size range coining depth. This standard is revised as follows. ensuring the coining width not less than 90% lead width of the strip Under parts, coining depth of no more than 30% of the thickness of the material, its reference value 0.015mm ~ 0.06mm; --- The "metal gap" to "insulation gap" (see 4.2.7), and revised the standard for "insulating gap" requirement. the original standard gauge Given "the maximum fine on each side projecting pressure does not exceed 0.051mm, limit metal clearance requirements shall be governed by" the standard was changed to "two adjacent fine Spacing and fine-nip zone between the endpoints and the endpoint chip bonding interval interval is greater than 0.076mm "; --- Revised standard on the "die attach area slope" requirements (see 4.2.9). the original standard were provided for in the fight and did not play the concave recess Maximum slope member under the provisions of the standard uniform for the maximum inclination in the length or width of each size 2.54mm 0.05mm; --- Revised standard on the "die attach area flatness" requirements (see 4.2.11). The original flatness standard 4.2.8.2 chip bonding region 4.2.2.2 Repeat the original standard, this standard be deleted. This standard canceled the original standard 4.2.2.2 each 2.54mm chip bonding The length of the restricted zones; --- Revised standard on the "glitch" requirements (see 4.3.1). cancel the original standard different even in different regions within and outside the vertical ribs burr Requirements, the standard uniform provisions of 0.025mm; --- Revised standard on the "pits, dents and scratches" requirements (see 4.3.2). increases in raw scratches on the basis of criteria relating to Claim; --- Revised standard on the "local silver layer thickness" requirements (see 4.4.1). the original standard specifies only a partial thickness of the silver layer, this Standard on the local silver layer thickness and any point were provisions; --- Revised standard on the "appearance of the coating" requirements (see 4.4.2). In the original standard, based on the appearance of the coating increases the relevance Claim; --- Added "copper peel test," the relevant requirements (see 4.6); --- Added "Silver peeling test" the relevant requirements (see 4.7); --- Standard "5 Inspection Rules" in the corresponding modification of terms, and an increase in appraisal and approval procedures relating to quality conformance inspection content; --- Amend the relevant requirements of the standard for "storage". the original standard plated shelf life of three months, the provisions of this standard is 6 months (See 7.2); --- Increasing the normative Appendix A "lead frame mechanical measurements."
