這篇文章有點長
主要是給想進這家公司當設備助工,卻又不清楚實際工作情況的人當參考
我只是隻菜鳥,接下來我要提的是我這幾個月在黃光部門工作的心得
又因為是菜鳥,所以淺談,只適用比我更菜的鳥
-
會想寫這些主要是因為網路上能得到的相關資訊實在有點少
包括我進這家公司前向學長和朋友詢問設備助工的工作內容
得到的都是「清機」、「保養機台」之類滿籠統的答案
這些只是其次,所以之後再談
我想大多數的人跟朋友打聽這家公司時
應該很常聽到「很操,別來」這類回答
但因為錢實在很多
聽到這種回答的時候有些人心裡會想「我不怕操」
在這種想法出現的同時
請先問問自己對「操」的定義是什麼
你不怕的是哪種操
我認為這超級重要
程度更甚於你的工作內容
因為你即將面對的「操」很有可能超乎你的認知
這點我想不只是助工
想進來當工程師的人也可參考
首先,你會進入恆溫的、充滿化學品的無塵室
不算熱,但也不到冷
要進無塵室就要穿無塵衣
那你知道無塵服長什麼樣子嗎?
你認為你能在不吃不喝不上廁所的情況下穿著它多久?
你能想像自己已經穿著無塵服戴著口罩手套
卻還要再穿上一件密不透風的防護衣嗎?
而且,通常你需要穿上防護衣的時候,就要戴上防毒面具
還要在你已經戴了一雙橡膠手套的手上再加一層防酸鹼手套
這些裝備全部穿上去,你能忍受多久?
你說你懶得穿,反正有戴口罩
我這些日子接觸到的化學品,通通都是一開瓶味道馬上飄出來,擋都擋不住的
這些東西吸久了身體會出什麼狀況,沒人敢跟你保證
工安督導這種形式上的我倒認為不重要
再來,萬一中途想上廁所或想喝水
光是脫掉這身裝備走出無塵室大概就要五到十分鐘
而你上完廁所喝完水
回到無塵室裡還要再穿一次才能繼續你的工作
我個人的經驗是連續五天沒吃午餐,中間也沒有出來上廁所
有時候早上九點進無塵室後就穿著上述所有裝備在裡面待到晚上快七點
所以,你對操的定義是像上面這樣?
還是坐在辦公室對著電腦螢幕到三更半夜?
如果這跟你想像中的操不太一樣
那也許你該謹慎思考自己是否適合這樣的工作
-
最重要的講完了,再來談談工作內容
先簡單說一天的行程
早上八點半到公司→課上交接(夜班交接給日班)兼分配工作→進無塵室→
午餐/午休→進無塵室→課上交接會議(日班交接給小夜班)→下班
如開頭所說的那些很籠統的答案
助工進無塵室就是幫忙清機跟保養機台
連腳踏車都要定期保養,更別說生產晶圓這種精密產品的機台
我的部門是黃光
機台的主要功能是靠機械手臂把晶圓個別傳送到機台的每個小房間
用底座吸住後高速旋轉,再由幾支噴嘴將光阻液等等噴在晶圓上
想像今天有一個臉盆,有根棒子黏著飛盤在中央旋轉,你再拿一支槍頭持續噴水
藉由旋轉讓光阻液塗佈均勻後,把晶圓傳送到一個鍋子裡加溫
加溫完畢,送到最後一間小房間裡冷卻,冷卻完再送回裝晶圓的盒子裡,至此結束
既然是無塵室,整個過程是不允許有太多髒東西沾到晶圓上的
水留在臉盆上會有水漬,抽油煙機久了也會有汙垢,這些都有可能是髒東西的來源
定期去換臉盆跟擦汙垢,就是助工的工作
保養的週期各自定義
有些機台沒兩三天就髒,所以設定片數,例如RUN完200片就保養一次
有些機台一個禮拜就髒,所以每週保養一次
有些機台兩個禮拜才髒,就雙週保養一次
但不管週期是什麼,總會有一個更大的
像週保再來是月保,月保再來又是季保
保養項目只會更多,不會更少
拿我們的機台當例子
週保就是換臉盆跟擦抽油煙機,確認機械手臂、噴嘴、整體環境是否有異常等等
臉盆跟機台連接的地方有抽氣管
久了髒東西會卡在裡面,壓力出現問題,機台就會alarm
抽油煙機也要定期分解,確認有沒有汙垢卡進更深入的地方
否則壓力出現問題機台一樣會alarm
因為拆這些東西很花時間,所以這些項目就會加在月保和季保裡面
講完項目,接下來講時間
保養是有限時的,一樣拿我們的機台當例子
週保表訂四小時,月保八小時,季保十小時
這些都只是「表訂」,實際做起來哪些機台需要多久時間你多做幾次就知道
更別說資深的學長,你單位的領導者(以下簡稱老闆)
甚至是製造部(也就是作業員/課長)
我們最煩的機台,一個人在最仔細的情況下做實際上差不多兩個多小時
你沒看錯,我是說最仔細的情況下
如果你很敬業,那你理應每次都是在這情況下做保養
那什麼時候沒辦法讓你仔細?
不外乎就是製造部要趕貨量的時候
在這行業,產能就是一切
製造部要趕貨,你老闆好一點就嗆他們保養沒做好責任他們扛
你老闆不敢就會打電話催你做快點
因為每個機台的狀態都會有系統記錄,用來控管機台的有效時間
今天你把狀態掛成保養,保養這個狀態掛了多久一查就知道
所以保養用掉太多時間影響產能,就是設備的問題
萬一你老闆被製造部點名,他就要去生產會議上解釋
至於要怎麼做快點,這就靠你的經驗
你一天被分配到的可能不只有一台,還都是週保
有時候一台都還沒做完,製造部已經把你負責的另外一台掛成等待狀態了
哪些地方根本不會髒,只要看過就好
哪些地方特別容易髒,需要仔細檢查
這個環節其實非常無奈
保養不只是做完就好
保養完還要由製造部來測機
就是拿空白片去檢查你的機台保養過後是否達到RUN貨的理想狀態
一旦測機不過,你就要去檢查機台
檢查完機台又要再交回去測機
在測過之前是完全不能RUN貨的
因此測機的這段時間和你所使用的保養時間一樣不算在機台的有效時間內
一旦花了太多時間,就看你怎麼跟老闆解釋了
-
再來說說值班
我們這裡值班分兩種
一種是助工值班,另一種是值工程師的班
助工值班就很單純,運氣好一點的不用幫忙保養
但如果機台出問題,像是上面提到的某機台壓力異常
或是製造部定期的測機沒過(通常是太髒)
這時候值班的工程師就會打電話給你,請你去幫忙換臉盆或擦抽油煙機
還有每天換下來的臉盆要送出去洗,洗好的要收回來
無塵布、防酸鹼手套等等沒了要去領
這些流程都要開單,因為不用保養機台或是分配到的機台少,所以都是助工值班負責
值工程師的班就有很多事情要忙
處理機況,整理每天課上交接資料,還有各機台狀態的記錄等等
雖然我有跟著工程師值班,也曾經幫他們處理過簡單的機況跟整理資料
但畢竟涉略不深,我就不獻醜了
-
介紹完工作內容,終於到下班時間了
下班時間是不是像很多推文說的五點半下班,真的是看單位
有些部門的助工不用參與交接,什麼時候保養完機台就什麼時候下班
前提當然是要五點半過後啦
像我的部門就因為助工要參與交接,所以得等值班工程師出來交接完機況才能走
出來的時間看運氣,機況多,忙不過來的時候最晚快八點
機況少的話倒是六點左右就出來了
但交接通常也要花上一個小時左右
下班時間就落在這些區間囉
至於要不要輪班這我無法回答,像我們課的助工剛開始是不用輪班
後來Loading變重,就開始拉人去輪大小夜
過一陣子又發現日班人不夠,所以只剩下日班跟大夜在輪
還是一樣看單位啦
-
上述內容是我在黃光這部門工作的心得,哪個廠就不說了
半夜睡不著一打就打了這麼多
我想盡量講得詳細一點,希望能幫助不知道自己是否適合這份工作的朋友
因為我就是進來才發現不適合,做到九月初就離職了
學長們要鞭請小力,謝謝
