Wave Testing Solder Joint Failures Using Dye Penetration
Today the most common methods of inspecting solder joints on Ball Grid Array (BGA), Chip Scale Package (CSP) or Flip Chip is X-ray or side view inspection using a fiber optic system. Each has its advantages and disadvantages but a combination of both is ideal provided you can justify both pieces of process equipment.
Breakthrough in solar photovoltaics
The Holy Grail of researchers in the field of solar photovoltaic (SPV) electricity is to generate it at a lower cost than that of grid electricity. The goal now seems to be within reach.
A Palo Alto (California ) start-up, named Nanosolar Inc., founded in 2002, claims that it has developed a commercial scale technology that can deliver solar electricity at 5 cents per kilowatt-hour.
Engineering a better light bulb
The lightbulb has remained virtually unchallenged since Edison invented it more than a century ago, but now scientists believe that zinc oxide�the same chemical that keeps diaper rash at bay�could provide a much-needed alternative to the inefficient lights that dominate our homes.
BEST Instructors have put to video demonstrations of common hand soldering 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.
In a few weeks I will receive an AOI machine. My concern is to know where is the best location for this machine in the complete assembly line. Here is a description of what I have :
Auto loader - Printer - Chipshooter PNP - Multi fonctionnal PNP - Reflow - Manual assembly - Wave - ICT.
Lead free profile
Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got.
The equipment that I used:
CP6 Nozzle sticking
I had a similar problem on another machine. It turned out to be the wrong oil used on the nozzle shaft. This oil was a higher viscosity, which caused the nozzles to stick at start-up. After the machine ran for a few minutes everything returned to normal.
