Leaded Solder Paste

Solder Paste

At Aarkay under UZHI brand we are manufacturing high quality Solder Paste for various applications in different-2 alloy composition.
Our Solder Paste has good Printing and rolling performance and leak printing performance even the spacing of solder pad is low to 0.4mm , can also complete a exquisite printing. Can complete continuous printing for a long time almost without collapse after printing for a few hours small viscosity change SMD Components are not easy to move.
Excellent soldering performance can complete a good wetting in different parts Less residue after soldering transparent appearance high insulation resistance do not corrode the PCB and meet the disposable requirement. Better ICT Test performance will not appear the false judgement.
We have Leaded & Lead Free Solder Paste available in different -2 alloy Compositions, reference table given below if needed other than this please let us know, products are available in different -2 ball sizes as per the need of customer.
