"Make" versus "Buy" decisions happen on a nearly daily basis in business. One of these type of decisions EMS providers or OEM manufacturers of electronics assemblies faces is that of reworking and repairing circuit boards. In this newsletter we point you in the direction of a few helpful tools in making this decision.
We also welcome Laura Ripoli to the BEST staff. Laura brings with her a vast experience in serving customers in the electronics industry. She is a welcome addition to the BEST team.

When determining actual rework costs, it is always a good idea to consult with your accounting department. You should obtain from them a "fully burdened" overhead rate per rework associate that can be used as a basis for your calculation. Work with them to obtain the cost of equipment and training. Make sure that you get a handle on scrap costs, which in many cases is the largest single component of total rework cost. Once you have calculated the costs required as inputs to the cost model, you can calculate the costs of a rework job. BEST has worked with a cost accounting firm to develop and research national averages as default values to this model. Use this tool to help you make well-informed "make" vs "buy" decisions in terms of rework projects.

A new technique which allows you to use the SAME soldering tips in a mixed alloy environment has been developed by BEST. BEST's newly developed "rinsing" technique allows you to stay within the RoHS guidelines for rework even when switching between lead-based and lead-free solders.
The study, which measured the presence of lead on the tip after subsequent "rinsings", found that a (4) time rinse sufficiently can reduce the lead content to below the RoHS 0.1% lead by weight guidelines.

The staff at BEST has developed a variety of visual aids to help BEST soldering techs make the transition to a "mixed" facility which includes both tin-lead as well as "lead free" hand soldering operations. These cue cards, t-shirts, work orders and posters all have the common theme of using red and green colors to differentiate tin lead from our "lead free" work.
The color coding is a quick way to remember the meaning of the two slogans "RED IS LEAD" and "GREEN IS CLEAN" (trademark pending). For instance a RED sticker on a work order indicates that the solder alloy and process to be used is lead-based. A GREEN sticker indicates the environmentally-friendly "lead free" solder and process is to be used. If you would like a sample card as a means to help remind your staff please call Laura Ripoli at (847) 797- 9250
