BEST Video Soldering Tips

Check out the newest gold cup wire insertion and prep tips. BEST Instructors have put together video demonstrations of common hand soldering tips and skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather, they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while. 

 
BGA Inspection
Inspection of PWBs

Visual "Referee" Inspection
If you need a "referee" resource when clarification is required regarding a PCB or wire harness acceptance standard interpretation, BEST can be that resource. Our Master Instructors, who are military trained and have been instructors for the IPC A610 courses for many years can provide a "third set of eyes" when an issue arises in the PCB assembly process. We can provide a detailed report for refereeing purposes.  When you need an outside expert opinion, or when you need to determine the existence of a PCB assembly process problem.

Endoscopic Inspection
Several characteristics of the solder ball can be determined with an endoscopic inspection tool. The actual standoff height, as well as degree of warpage, can be measured. Capture software allows for both absolute and relative measurements. This allows BEST to help you set up QC measurements for real-time references for the boards being inspected. Several defects can be measured and recorded via .jpeg or .mpeg images. For example, solder joint cracks in connections inside, outside or under the component body can be seen.

Electronic Voting Machine


As the political season kicks into high gear the following is a discussion on the use of electronics in the voting process in the US.

Direct recording electronic (DRE) voting machines were introduced to enhance the voting process, but their helpfulness is still contentious. Originally developed in the 1970s, DRE usage has increased nationwide in each subsequent local and federal election. However, it was not until after the 2000 U.S. Presidential Election's issues with pregnant and hanging chads and the passage of the 2002 Help America Vote Act (HAVA) that voting technology became more widely argued. There is considerable debate between election officials, computer scientists, politicians, advocates for the disabled, and concerned citizens as to whether electronic voting machines improve the voting process or not.

Some proponents argue that electronic voting machines make the voting process more efficient. They publicize DREs as being secure, able to unambiguously capture the intent of a voter, capable of preventing residual votes, reliable, easy to use, and accessible to disabled, illiterate, and non-English speaking voters.

Some opponents of electronic voting machines believe DREs give too much power over public elections to their private manufacturers, are vulnerable to hacking and other forms of tampering, do not allow for meaningful audits and recounts, and do not offer voters a trustworthy form of verification.
