Hi, I need help on how to address the solder wicking on the samtec searay connector after reflow resulting to open solder joints on thick and thermal heavy PCB (4.4mm and 6.3mm). I increased my solder paste thickness to 8 mils, the connector is manua

Hi Evtimov, Thanks again! The solder wicking/open solder joint is not actually gross rejection, it is only a few and appeared random (difficult to trend the location of the opens), what is perflexing is that i have this 1 or 2 open solder joints sur

We have had a few large human error, wrong placement in the SMT set up over the past year(same package size placed in the wrong feeder position to where it goes unnoticed) and we are trying to look for possible process improvements to prevent this fr

There are two areas that are important when discussing cooling rate. One is the rate thru the liquidus, where a fast rate produces small grains in the metal and a slow rate results in larger grains. Although smaller grains are stronger normal SM

The odd form assemblers are extremely slow compared to the Axial & Radial UIC machines. Also there is a big cost for feeders. Key question is what is the max axial & Max radial feeder count on your biggest job and that will quickly tell you how man

Aurash, we own Yamaha machinery but just throwing it out there...are the movements of the motors smooth or with friction? Is it possible that the linear screw rods (as in our machinery) require to be lubricated? There are special lubricants for each

Hi Hearse, I currently use a MY600, with a AG Ejector which can place dots between 0.33 and 0.52 mm. The differences for a MY600 with placing small dots is down to ejector and paste. To be able to place dots as small as 0.25 mm, you would need an

The software is crazy expensive for some of this stuff and in many cases you could develop the bits of it you actually use in-house for a fraction of the cost. Unless you are a company who really like this level of process control and you run multip
