. Defines the processes required to be followed to manufacture. This document identifies the classification level of nonhermetic solid-state surface mount devices SMDs that are sensitive to moisture-induced stress. 11 Scope This standard prescribes test methods defect definitions acceptance criteria and illustrations for assessing the solderability of electronic component leads terminations solid wires stranded wires lugs and tabs. J-STD-020 covers components.

Version of J-STD-020 JESD22-A112 rescinded or IPC-SM-786 rescinded do not need to be reclassified to the current revision unless a change in classification level or a higher peak classification temperature is desired. J-STD-020 covers components. JEDEC J-STD-020 March 1 2008 MoistureReflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices This document identifies the classification level of nonhermetic solid-state surface mount devices SMDs that are sensitive to moisture-induced stress. The classification level enables proper packaging storage and handled to prevent potential damage as a result of moisture-induced stress during soldering operations and or repair operations.

IPC certification plays a key role in bringing value to the electronics industry. The purpose of J-STD-020 is to identify the moisture sensitivity classification level of non-hermetic solid state surface mount devices SMDs. Or J -STD -020 may be reclassified as non-moisture sensitive level 1 without additional reliability stress testing eg JESD22 -A113 an d JESD47 or the semiconductor manufacturers in-house procedures. The term SMD as used in this document means plastic.

Preconditioned shows that a different condition is required to obtain a dry package. IPCJEDEC J-STD-020 Revision C Proposed Standard for Ballot January 2004 4 37 Weighing Apparatus Optional Weighing apparatus capable of weighing the package to a resolution of 1 microgram. This standard also includes a test method for. The Peak reflow temperature is specified in dependence of package thickness and the package plastic volume.

The Pb-Free Process Classification Temperatures Tc table in the IPCJEDEC J-STD-020 standard lists the temperatures for leadfree process which are shown in Table 2. It is used to determine what classification level should be used for initial reliability qualification. NOTE 2 If the preconditioning sequence is being performed by the semiconductor manufacturer steps 311 312 and 314 are optional since they are the suppliers risks. J-STD-020 -October 1996 JEDEC JESD22-A112 IPC-SM-786A -January 1995 IPC-SM-786 -December 1990 IPCJEDEC J-STD-020E MoistureReflow for Nonhermetic Surface Mount Devices A joint standard developed by the IPC Plastic Chip Carrier Cracking Task Group B-10a and the JEDEC JC-141 Committee on Reliability Test Methods for Packaged Devices.

This document identifies the classification level of nonhermetic solid-state surface mount devices SMDs that are sensitive to moisture-induced stress. IPC Certifications Deliver Consistency in Manufacturing. IPC JEDEC J-STD-020 is used to determine what moisture-sensitivity-level MSL classification level should be used so that surface mount devices SMDs can be properly packaged stored and handled to avoid subsequent thermal and mechanical damage during the assembly solder reflow attachment andor repair operation. Also available in Chinese Language See J STD 020 CHINESE.

JEDEC JESD22-A112 IPC-SM-786A -January 1995 IPC-SM-786 -December 1990. SMD packages classified to a given moisture sensitivity level by using Procedures or Criteria defined within any previous version of J-STD-020 JESD22-A112 rescinded IPC-SM-786 rescinded do not need to be reclassified to the current. MoistureReflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices - December 2014. JEDEC J-STD-020 Revision E December 2014 - MoistureReflow Sensitivity Classification for Nonhermetic Surface Mount Devices This classification procedure applies to all nonhermetic SMDs in packages which because of absorbed moisture could be sensitive to damage during solder reflow.

It is used to determine what classification. The following classification gives a clear idea about the different elements involved in these two standards. These certification programs built around IPC standards developed and approved by industry are delivered in a classroom setting by IPC certified trainers. According the IPCJEDEC J-STD-020 standard revision at that time.

052016 Also available in Hardcopy format. Passing the reject criteria in this test method is not sufficient by itself to provide assurance of long term reliability. Upon successful completion of the training and. Annex B provides an overview of major changes from Revision C to Revision D of this document.

7500 3750. Once identified the SMDs can be properly packaged stored and. Institute of Printed Circuits. IPC 3000 Lakeside Drive Suite 309S Bannockburn Illinois 60015-1249 Tel 847 6157100 Fax 847 6157105 This Page Intentionally Left Blank.

Refer to J-STD-020 for procedures on running absorption and desorption curves. IPC JEDEC J-STD-020 is used to determine what moisture-sensitivity-level MSL classification level should be used so that surface mount devices SMDs can be properly packaged stored and handled to avoid subsequent thermal and mechanical damage during the assembly solder reflow attachment andor repair operation. This apparatus must be maintained in a draft-free environment such as a cabinet. 3103 North 10th Street Suite 240S Arlington VA 22201- 2107 Tel 703 9070026 Fax 703 9077501.

Standard by JEDEC Solid State Technology Association 12012014. J-STD-001 however is a specific standard that defines materials and processes for soldering to ensure quality solder joints and a reliable assembly. J STD 020.
