Pajisjet gjysëmpërçuese - Metoda prove klimatike dhe mekanike - Pjesa 20: Rezistenca e SMD - ve të futura në material plastik ndaj efektit të kombinuar të lagështisë dhe nxehtësisë së saldimit

Semiconductor devices - Mechanical and climatic test methods - Part 20: Resistance of plastic encapsulated SMDs to the combined effect of moisture and soldering heat

Scope

IEC 60749-20:2008 provides a means of assessing the resistance to soldering heat of semiconductors packaged as plastic encapsulated surface mount devices (SMDs). This test is destructive. This second edition cancels and replaces the first edition published in 2002 and constitutes a technical revision. The main changes are as follows: - to reconcile certain classifications of IEC 60749-20 and those of IPC/JEDEC J-STD-020C; - reference IEC 60749-35 instead of Annex A of IEC 60749-20, Edition 1; - update for lead-free solder; - correct certain errors in the original Edition 1.
