Depending on the how you plug the via, the void level can significantly affected. If you have via plugged from the bottom side; i.e. opposite side of the component, you will see alot of void due to entrapped air in the via hole. I found work best wh

If you want to buy a Juki machine or any machine for that matter, then be ready with money in hand and you set the price you are willing to buy at today. In my experience alot of Asian Brokers want your best price up front, and then tell you it's too

Hi Gani, looking at the HASL icture and the poor wetting of the solder over the pads I would imagine that the HASL coating is very thin on the pads and in actual fact isn't 'solder' but is tin /copper intemetallic and this has poor solderability. It

Possible, but difficult. What algorithm programs are you referring to? Mirtec and YesTech both utilize algorithms in their respective software. The algorithm is simply a series of instructions to perform the inspection. In this case, rules-based,

Who Cares... Mix Away! Although you should not mix different Solder Pastes' together in a container or on a stencil (Mostly due to the flux, although solder sphere size and shape could cause an issue), mixing solder brands or chemistries on a board

Yes, we have had this happen with certain solder masks over the years. Hot air gun is the best solution we can find if the oven doesn't do it. Back in the day when we had a vapor degreasor, freon based solvents would also remove the clouding. Let

The 5 thou standoff of your SOIC is probably the minimum. We wouldn't be surprised to see 10 thou. With this, you could have maybe a 6 thou gap between printed solder paste and the bottom of the heat slug. So, you're expecting the rabbit ears of p

Hi Jack, I haven't progressed that much on the reflow project.I'll be working on it in two weeks. Although, I have few vendors that I've been communicating for more info about vapor phase reflow ovens. See the following list: Wenesco Sintronex AICT

Also please contact Rehm Thermal, they make best Vapor Phase systems in terms of cost of onwership - less galden usage than Asscon or IBL, have more controllable ramp rate control vs the other vendors also...use patented galden injection on demand an
