Latex Gloves – Are You Allergic?


Many industrial manufacturing environments require workers to wear protective gloves, including during electronics and medical device production and assembly. Latex gloves not only protect workers from harmful chemicals but also protect products from worker contact and contamination during manufacturing Read more

Metcal’s CV-5200 Connection Validation Soldering Station Changes Everything


You may or may not have heard about Metcal’s new soldering station, the CV-5200. The evolutionary tool removes much of the reliance on visual inspection of hand-soldered joints and adds a second, more technology-driven method for validating a successful Read more

Weller Soldering Tip # 8

Weller Tip Tinners Tip tinners can cause premature degradation of tips when used too often. The aggressive nature of the fluxes used in tip tinners can contribute to short life expectancy of tips. Use tip tinners/activators when a tip is beginning to exhibit signs of non-wetting, but do not use them to repeatedly re-tin the tips.  Many companies use tip tinner in a controlled tool crib environment where tip maintenance can be performed properly without inflicting unnecessary damage to the tip.

Flux Pen Liquid fluxes are often used to assist with soldering, and in most cases it’s because they are readily available. When using liquid fluxes, just make sure the flux is compatible with hand soldering. One common mistake in hand soldering applications is to use a liquid flux designed for a semi-automated process such as wave soldering. Those fluxes are not formulated for hand soldering, more specifically they are not designed for direct contact with a tip. Flux pens that are compatible with hand soldering applications will distribute the correct amount of flux each time the pen is used which leaves behind less residue and fewer solids.

Confirm that the manufacturer’s recommended soldering temperatures match the range of temperatures that are required in the application. One additional suggestion is to try and lower the operating temperature of the tools, even if the soldering dwell time is lengthened by several seconds. This will also assist in extending tip life; 90° F lower in temperature can improve tip life by more than 50% when no other variables are introduced.

When using pre-tinned devices and HASL (Hot Air Solder Leveling) or OSP (Organic Solderability Preservative) on PC Boards, using a very active rosin core solder is not necessary. Using a high activity level flux works well on heavily oxidized metals such as bare copper or other non-tinned or non-plated metals, but is not readily suggested for standard electronic assemblies. Use a flux that is designed for the metals that are being joined and keep the activity level to a minimum to help extend tip life.

Fluxes containing a “high solids content” are one of the largest contributors to surface contamination, which leads to the blackening or charring of fluxes on a soldering iron tip. This in turn, can cause a tip to be rendered useless in a matter of hours, if not minutes. If proper research is done, solder manufacturer’s technical data sheets or MSDS sheets will indicate the % of solids. Extremely high temperatures will also accelerate the surface contamination process.
