《舊文複習》IMC層是PCA焊接的必然物卻也是焊錫結合力(bonding-force)最脆弱之處
一般來說，一個良好的PCA焊錫形成，其焊錫結合力最脆弱的地方為IMC(Inter-Metallic Compound)層，IMC層是一種金屬化合物，IMC更為形成良好焊接的必然物，工作熊之前將IMC層形容為男女結合後所誕下的小孩，這裡你可以將這層IMC想像成黏合磚塊與磚塊之間的水泥層
Pic - Perintah Kawalan Pergerakan - stay put Everyone ...
The Government is ordering Everyone to stay put at home for the next 2 weeks which is an impossible task . Many are restless and defy the orders still seen in public , buying loads of groceries , some balik kampung to visit their loved ones and many more ...
Little did we realise how dangerous this Covid-19 could be ... everyday the number of those infected and detected is rising .
I try to look at this quarantine on a positive note instead ...
Just loved the bonding time and the many things I could do with the kids at home ...
1. Doing revision together with the Girls
This is the time Bella could hafaz her AlQuran in a continuous manner . Also guiding Tasha on her Jawi and Tajwid .
2. Making an effort to Solat jamaah together with the kids and stick to the routine . Always terlepas since the girls are occupied with Schoolwork .
3. Teaching the Girls new Sports . For the first time Bella & Tasha are playing badminton by our lawn ... Haha while the Boys are kicking football everywhere .
4. Bike ride within our Compound
Just taking the kids on my 400cc Scooter within the gated area can be fun .
5. Crafts & Arts with the Boys
Daily colouring and painting with Adam & Noah . The Boys just loved playing with crayons and paints .
6. Playing in the rain
It’s always fun when it rains and the kids just love playing in the muddy puddles .
7. Cooking lessons for the Girls
It’s time to teach Bella & Tasha the proper technique on how to cook the simple stuffs like nasi goreng , scrambled eggs , baking cakes etc . Dah jadi anak dara these 2 Girls .
8. Reading their favourite Book
We have a library full of unread books . Tasha is still on her ‘ Captain Underpants ‘ and Bella with her ‘ Teenage Themed ‘ Books .
9. Climbing trees and playing with nature
The Boys just loved climbing and there’s so many trees at the back of our house .
10. Completing my parenting Book
Just some final touches before publishing them .
Hence Everyone ... take this quarantined time to create bonding time with the family . Avoid going out to minimise contact , wash your hands thoroughly and stay home .
Just sharing .
Love As Always
