#BREASTFEEDING (BF) - 6 months into motherhood, still one of the most daunting things I’ve faced. Becuz no one can prepare u for what’s to come or how u do it exactly. I’m lucky that my baby can naturally latch on. Here are some common questions that a first time mom/mom to be will always ask about breastfeeding🤱:
Q1️⃣ Is BF painful?
Won’t lie, BF is sometimes painful. There are good days & bad days. Cracks, blisters, bleeding, u name it.
Q2️⃣ When should I breastfeed or use breast pump?
It depends. I found it very time consuming to breastfeed and can’t see how much Amias is drinking, which is very problematic in establishing the feeding schedule. That’s why I do pumping all the time!
🌟P.S. Double pumps save soooo much time! Can’t emphasis how important this is
Q3️⃣How can we have more & quicker milk flow?
Stress can decrease your milk supply! I hired a lactation consultant before - 佢好大力咁幫我通乳，我喊到形容唔到幾痛，加上佢逼我要有一個好嚴格嘅 BF schedule，我同BB都好辛苦，壓力更加影響milk supply🤦🏻♀️
After the confinement lady left, I resorted to pumping exclusively; it helped massively.
💫I produced the constant highest amount of milk
💫The right pump with the right stimulation helps empty the breast, which is key to⬆️milk supply
💫For me, it is really important to know exactly how much milk my son consumes, 解決咗依個問題，個人輕鬆咗，奶量就會多
Some pumps that are too forceful (有時硬係覺得開大力啲就泵得清) could cause blisters, bleeding too. It happened to me😢 But here, I want to share my experience of using @philipsavent double electric breast pump. One of the key features is its Natural Motion Technology which can stimulate the breast to express milk just like baby’s natural suckling motion. With applying the right amount of nipple stimulation and suction for max the milk flow.
I was quite surprised by the amount it pumped & how gentle it was to the breast/nipple, especially with this soft and adaptive silicone cushion, I didn’t feel any pressure or pain.
BF Mamas, Jia You!💪🏼💪🏼💪🏼 It’s a tough job, but there is always a solution, so don’t give up! Sending good vibes!

latch up解決 在 Re: [問題] 數位電路閂鎖(latch up)的問題- 看板Electronics 的推薦與評價
※ 引述《gyamwoo (Gyeon-woo)》之銘言：
: 最近在測量電路，結果發現數位電路的電流超大，6mA以上
: 至少是比其他區塊都還大。當然數位電路訊號出不來才去量
: 我自己推測是latch up，若有正常動作的話電流不會超過1mA
: 上網查了一下似乎是這樣，latch up會產生大電流。
: layout的時候也沒有遇到latch up的drc error，是因為我不
: 知道是用什麼方式去畫layout才沒遇到latch up的呢…
: 如果真的是latch up，這樣電路還有救嗎？
: 拜託強者為小弟解惑~thx~
我非真強者，只是路過湊過來看樂熱鬧的鄉民~
1.有些Design rule是找不出來這類latch-up的問題，不過機率很低。
2.latch-up所造成IC失效的程度，重則是不可逆的毀損，輕則只要電源重新power-down
過一陣子就ok。
3.容易發生latch-up的元件，如transmission gate，尤其他的source或是drain直接
與VDD或VSS相連。
4.你只要了解latch-up的原理，就可以避免它，這點，我就不在這多說明，書本與
網路上都有資料。最直覺的方法就就是減少橫跨Base與Emitetr端之間的寄生電阻值
從而減少觸發latch-up的電流。個人認為，你的數位電路應該有些地方是直接面對
大電流的輸入，如上述提及的傳輸閘，你可能將它的drain或是source接到Vdd or Vss
一旦突來的大電流很容易就會造成larch-up。雖然這是CMOS IC常發生的，不過，也
因於此，很多design rule都有針對它去防範。
底下列舉一些layout技巧，希望對你有幫助。
1.避免電源的跑線使用高阻值的材質(diffusion或是ploy)，尤其是要接到substarte或是
well contact，貪圖一些捷徑可會得不償失，強烈建議還是乖乖地用金屬導線。
2.substrate或是well的contact盡量接近元件本身，彼此之間越近越好，而且數量越多
越好，降低Rsub與Rwell阻值。別打個一兩顆，這不是用來作口碑或是作功德用。
3.相同類型的電晶體盡量畫在一起，避免東一塊西一塊，讓latch-up產生的條件易產生。
4.把內部電路盡可能搬離PAD附近的區域，尤其該PAD是要用來灌大電流
5.特別注意一些電晶體的source端，其substrate與well是不同電位所在的區域。
另外，一些面積比較大或是切換快速的電晶體，容易從substtate引入nosie，像
時脈產生器(clock generator)或是output buffer(輸出緩衝電路)，這裡的guard ring
可千萬不能省！！！若是為了穿線而將guard ring打斷，不要忘了只把一邊的ring
接上電位，另一邊卻別忘了接！
最後，如果你想要找出latch-up的位置，最直接的方法就是拿去作EMMI（Emission Micro
scope）或是OBIRCH（Optical Beam Induced Resistance Change ）
找出那一塊電路出錯，然後再對照layout。若想不出，就自己畫個剖面圖，找找上頭
的寄生BJT。換個角度來看，最後若找出真正原因，這次你繳的學費算算是夠本了，
別太沮喪。

在臺灣，何謂R&D工程師?
1.Reverse and Decap :IC反相工程，去膠，打開封裝，拍照，複製電路佈局。
2.Resign and Die :沒死的就操到辭職，沒辭職的就操到死。
3.Rework and Debug :計畫永遠跟不上變化，變化永遠跟不上老闆的一句話!
4.Relax and Delay :太過於輕鬆(Relax)，那麼就會Random Death (隨時陣亡)
但是外派到大陸的臺彎郎，晚上是R (鴨)陪客戶，白天是D (豬)任人宰割!
