In video two we're going to be covering the SMT process
8
and I've broken this down into three separate sections so this will be part one of three.
9
In part one we're going to be looking at the solder paste application, the component placement.
10
In the SMT process part two video we're going to be looking at the reflow soldering process
11
and the cleaning process or the phase.
12
In part three of this series of SMT process we're going to be covering the electrical testing
13
and then in video five we're going to be covering the inspection methods and common defects.
14
In particular we're going to be looking at solder paste issues,
15
pick and place issues, wave soldering issues.
16
In video 6 in the series we're going to be covering reliability testing.
17
We're going to be looking specifically at reliability and durability,

מהי טכניקת השאדואינג?
שאדואינג היא טכניקת למידת שפה מבוססת מדע שפותחה במקור להכשרת מתורגמנים מקצועיים ופופולרית על ידי הפוליגלוט ד"ר אלכסנדר ארגואלס. השיטה פשוטה אך עוצמתית: אתה מקשיב לאודיו באנגלית ילידית וחוזר עליו בקול רם מיד — כמו צל העוקב אחרי הדובר עם עיכוב של 1–2 שניות בלבד. בניגוד להאזנה פסיבית או תרגילי דקדוק, שאדואינג מכריח את המוח והשרירים בפה לעבד ולשחזר דפוסי דיבור אמיתיים בו זמנית. מחקרים מראים שזה משפר משמעותית את דיוק ההגייה, האינטונציה, הקצב, הדיבור המחובר, הבנת השמיעה ושטף הדיבור — מה שהופך אותו לאחת השיטות היעילות ביותר להכנה לIELTS Speaking ולתקשורת באנגלית בעולם האמיתי.
