修复设备，基板以现场试机通过为准，基板交用户后，用户必须在一周内通知承修方，如没有通过则交回承修方返修，否则视未通过。特殊情况不能试机（板），则客户方必须事先通知承修方。
Parts are soldered on the board onto metal pads, which happen to be connected to the board circuitry. This allows components for being interconnected. A board is often composed of one, two, or a number of levels of circuitry.
Enantiomers of chiral compounds have related chemical and Bodily properties, but could be metabolized by your body differently. This was checked out in bowhead whales (Balaena mysticetus) for two main reasons: These are big animals with sluggish metabolisms (indicating PCBs will accumulate in fatty tissue) and few research have calculated chiral PCBs in cetaceans.
