Plungers and needles are available upon request. A 30-guage needle is the smallest size recommended for dispensing SMT solder paste (Type 6 powder).
What is the ideal size for syringable solder paste?ĪMTECH offers 100 grams of paste in a standard 30cc syringe, as well as 35 grams of paste in a standard 10cc syringe.
When soldering silver or silver-plated component leads, adding a small amount of silver (typically 2%) to the solder helps prevent the silver found on the component lead from migrating onto the solder, which can result in a weak or brittle solder connection. When the moisture comes into contact with the component-lead, solder paste, through-hole, wire or material under elevated temperatures, the water can begin to boil, causing pin holes to be formed by trapped or escaping water vapor. Pin holes are formed by moisture that is trapped within or beneath the solder. Special care is required when storing flammable chemicals at elevated temperatures, especially alcohol and other chemical compounds that can expand when heated, which could create explosive pressure within the container. Flammable materials should also be stored in an approved flammable materials storage cabinet. Generally, flammable chemicals be stored at room temperature with normal humidity, unless otherwise specified. What is the best way to store flammable chemicals? For better dispensing control, consider using a tacky flux instead of an alcohol based flux. After a certain number of applications, the felt tip starts to wear down, so replacement tips are available. Use of a flux dispensing pen helps to solve this problem because the flux pen works like a marking pen, dispensing just the right amount of flux where needed. Dispensing flux into confined areas can be problematic.
