Once the solder paste has been applied to the printed circuit board, it is then passed into the pick and place machine where the components are added. The solder paste has sufficient tension that it holds the components in place. However care should be taken not to knock the board at this stage otherwise the components may move of fall off. Additionally the board should be soldered within a few hours of being placed, otherwise the solder paste may deteriorate. Purchasing solder paste Solder paste can obviously be bought in industrial quantities for large PCB assembly plants, but it can also be bought in smaller qualities. It can be purchased in tubs and syringes. These are particularly useful to applications like general or BGA rework areas or for small prototype assembly. Solder paste is widely used in PCB assembly - both in mass production and also for prototype PCB assembly. It provides an excellent method of applying the solder that is applicable to large and small forms of PCB used with care it enables very high quality soldered joints to be produced, however very careful control of the process is required if this is to be maintained, and any issues discovered need to be fed back into the process to correct the issue as quickly as possible.

SHENMAO America, Inc. is pleased to introduce the PF606-PW215 water-soluble solder paste. The company offers a full line of water-soluble fluxes and solder pastes for SMT and IC packaging applications. SHENMAO provides halide-containing and halide-free fluxes for tin/lead as well as lead-free solder alloys. PF606-PW215 boasts superior continuous high-speed printability that produces great solder paste print quality as well as a wide reflow process window for excellent solderability. Additionally, the paste has a long shelf and stencil life as well as excellent wetting and clean-ability. Benefits include: Anti-slump properties that remain 6 to 12 hours after print time Substantial deposition remains 12 hours after printing Tack force that remains at >130gf after 24-hour stand Paste activity that remains after 19-hour stand No flux residue after cleaning SHENMAO is dedicated to producing solder products including water-soluble and no-clean solder paste, laser solder paste, solder preform, cored solder wire, wave solder bar alloys and wave soldering fluxes.
