31, Due to its excellent pyroelectric, electro-optic and photo-refractive properties, strontium barium niobate (SBN) is one of the most potential lead-free ferroelectric materials.

32, So it is very necessary to study the wettability of lead-free solders and electromigration of solder joints.

33, Additives: vegetable-based emulsifier, lead-free drying agent (cobalt linoleate), methyl cellulose.

34, The product is lead-free environment, stable performance, high precision resistance can be directly replace conventional beryllium oxide resistance.

35, Several processings, grain orientation growth (TGG) and doping, which can improve performance of the bismuth layer structure lead-free piezoelectric material, are introduced.

35, Sentencedict.com try its best to gather and make good sentences.

36, The apparatus (1) enables copper which has dissolved in a lead-free solder comprising tin as the main ingredient to precipitate as an intermetallic compound to separate the copper.

37, But for hunters who are determined to take a shot, lead-free bullets are the "greenest" choice.

38, The methodologies for free drop test and bending test are introduced, considering the important effect of mechanical stress on the reliability of lead-free BGA packaging.

39, With the miniaturized and lead-free development of electronic products, higher demand is put forward about solder.

40, This lead-free fuel requirement, in turn, significantly reduces the amount of lead (and other metal additives ) in the atmosphere.

41, MCU control and high sensitive temperature detector integrated design. Instant heating at 350 oC within 10 seconds which satisfy lead-free soldering.

42, There is no free government inspector, there is no free lead-free paint, and there is no nicely priced catfish if it is unfit to eat.

43, Through the strict implementation of lead-free technology, we will continue to improve our product quality and continue to meet customer demand.
