Dear James
目前碰到一個客戶要求測試方式遵循J-STD-003B要求.但是測試時用的助焊劑
又和003B要求不同.所以出現了測試差異.如用003B的二號助焊劑做焊錫實驗是合格的
但是改用004 中的ROL1卻是不合格.正確使用方式是否為003B才正確.

003B中的2号助焊剂是专门用来测试的专用助焊剂，下面的表4-1中有详细的成份说明。而004中的助焊剂是生产用助焊剂，因此004中没有此类助焊剂。

Dear James
1在 J-STD-003B 3.2.2 中規定無鉛測試用的助焊劑應當為 2 號標準松香助焊劑
想請教表內的1號及2號助焊劑.是屬於 J-STD-004B 表3-2 中的哪一個類型?
2.若2號助焊劑是屬於ROM1 . 客戶要求使用ROL1類型助焊劑來做測試是否洽當.

Dear James
但是參照 IPC-A-610D 1.8 並未清楚寫出照度要求
是否在其他規格中有寫到呢?

Hi all,
IPC610中规定了放大镜的使用，并要求照度能满足要求。请问照度要求的具体数值应该是多少？
