Name:Lead series of water-soluble flux
Category:Chemical water
 
Detail:
-, Overview:
QD-2000 Series is the (clear, colorless - light yellow transparent liquid) water-soluble flux. This series of water-cleaning after the residue (NaCl/cm2) met the requirements of various electronic products.

Second, product features :
To meet the broad masses of the welding requirements of the electronics industry, the Company produced a series of water-soluble flux for the special electronic equipment manufacturers and meticulous preparation. Such as: 2, the transistor on the copper with tin, copper plant material tin (using models QD-2000-1), with iron-on components (the use of models QD-2000-2), Road board on the tin plate ( The use of models QD-2000-3), and so on. This series of products are good wetting ability and excellent effect on the tin, tin products for the welding of thin and light-on, no needle marks, stomatal and rough surface (not uniform formation), and other undesirable phenomena Produce, clean water (water temperature 60-80 ℃) no residue, very clean. This series of products for hand Baptist (magnetic cast steel components fixture welding, tin-280-320 ℃), magnetic cast steel fixture automatic soldering machine (tin-280-350 ℃, and tin-distance fixture 1-3 mm) and jet soldering Machine Welding equipment.
