The best way of keeping solder paste is put it into the refrigerator under the lower temperature of 2 8 with the sealed forms
22.
The operator should assure a shorter open time and make the paste be in good sealed status after we have taken sufficient solder paste once
23.
Do not touch solder paste bare - handed . remove with ethyl alcohol from body or clothes if contaminated by solder paste
24.
From this information the volume of solder paste required can be calculated , which can in turn be used to design the aperture dimensions
25.
Solvent may be easily vaporized when solder paste is contacted with air - conditioned current or wind and hence reducing its tackiness
26.
Smd environmental testing : tests - test : test methods for solderability of surface mounting devices by wetting balance using lead - free solder paste
27.
Attachment materials for electronic assembly - part 1 - 2 : requirements for solder pastes for high - quality interconnections in electronics assembly

Attachment materials for electronic assembly - part 1 - 2 : requirements for solder pastes for high - quality interconnections in electronics assembly
29.
And then take it from the refrigerator until the solder paste is back to the normal temperature with the sealed forms the operator may open it and use
30.
Trough the experiment , we probed to the suited mount method ( mount with 183 soldering paste ) and bonding technique ( ball bonding with the gold silks of 18 m in diameter )
