You can track the work load of contractors both on and offsite. A Web-based time clock can help you see what your online freelancers are doing with their time, and helps pay them according to what they have done for you. Those working in house should be trained on operating procedures, and management should regularly follow up with work that was done. These tips will help you hire and track contract employees, regardless of where their office might be.


The first step in the hiring process is to recognize when it’s worth it to interview a potential employee. Start by creating your ideal job description, which is like a set of details for the person you want to work with. Narrow down applicants based on how closely they meet your ideal criteria. It’s important not to disqualify too many candidates during this phase, as you might benefit from some on the job training if the candidate otherwise performs well. Once you’ve decided on who you want to interview, arrange a Skype call if you plan to hire remotely, or an in-person appearance if not. Have a set of questions that challenge the candidate to think on his or her feet.

Tracking Progress

Online time tracking is useful for candidates who work off site. It allows you to track their progress minute by minute, and pay them according to the time they devote to your projects. It’s also important to schedule regular status meetings, either over the phone or in person, so that you can determine what road blocks might be standing in the way of progress. Tracking progress also allows you to see what your employees can handle, and find areas for improvement. For instance, you may find that a certain contractor completes a specific task faster than others. Without tracking progress, you wouldn’t know to give that person assignments he is better at.

Chain of Command

When you have employees working offsite, especially those who use an online timesheet, it’s important to set up a chain of command. This helps handle disputes that arise during the work, like questions about hours or tasks. Designate a member of management responsible for handling all communications with your freelancers, and check up with this person regularly to make sure projects are getting completed on time and under budget.

Thermal Evaporation Versus Sputter Deposition

Summary: In manufacturing, vacuum coatings are used to give materials different properties.

In heavy-duty manufacturing, there are basically two kinds of vacuum coating systems used during production. These two systems accomplish some of the same tasks, but how they perform their duties makes a big difference. There is a definite question of which is best for your situation, but you can make a more informed decision once you understand the differences.

Thermal Systems

A thermal evaporation system superheats materials that will be used to coat a substrate. The substrate receives the coating rather passively as the materials settle. The chamber is cooled, and the materials harden on the substrate to form a thin coat. There isn’t much pressure involved, so this process isn’t useful if you need to add heavy layers of coating to something. Evaporation also has limits on the materials you can use, and temperature sensitive substrates can break down during the process if the manufacturer isn’t careful.

Sputter Systems

A sputter deposition system is generally more expensive than a thermal system, but it can add several important benefits. For one, sputtering allows for better step coverage. Even though sputtering is a complex process, it’s also easy to replicate and automate.

Final Thoughts

Sputtering is most useful when you need to apply a dense coating to materials. Thermal evaporation is useful for products that need only a thin film coating. You should also keep in mind what materials you’re working with, as some are more sensitive to temperatures than others.
