Glue application is widely used in my country.However, some companies want to save cost and remove the glue application. We are also using fixture to cover some components. It has no problem. Please try cleaning your fixture by alcohol or water.Brush

3d is good for initial verification that your screen printer and stencil is producing the desired paste height. 2D verification is more than sufficient during regular production. That being said, your best bet for a 3D machine is to go cheap - buy

In short this guys are not well updated on the new technology of SPI. True, 3D IN LINE SPI is no longer a slow machine. Try checking some brand like Cyberoptics,Synapse imaging,SEIMENS,KOHYOUNG and many others...they can match the speed os some mount

Jeremy, well said! Thanks for "validating" my theory... LOL I agree that the sampling frequency, AND methodology are key things with 3D inspection. 3D will give you some insight onto how your paste (rheology, viscosity, thixotropy)AND process are

$100K for this entire line. We are thinking of getting a Chinese made reflow oven that looks pretty good at $25K. Also, we need to deposit solder using a dispenser as stencil printing will be reserved only for higher volume boards. It will not be pra

If your product mix is similar in terms of thermal mass and componentry, find some standard setpoints (by doing a baseline profile) which will produce a thermal profile that's within the specs. of your solder paste and product. This approach usually

Profiling is product specific. An instrument called the OvenRIDER from ECD is for soldering machine quality management. See link below. This instrument measures various parameters of your oven to include thermal transfer efficiency. The concept is,

For what it is worth, we are purchasing a dispensing system including a Robotic Arm, Positive Displacement Valve (as opposed to volumetric displacement) and Controller. We have purchased this unit for doing lead free 20 mil dots at 30 mil pitch in s

Hi Loco, Good point!! The good old glass plate works just fine as long as the conveyor or carriers have L shaped fingers. A glass plate is usually about a � inch thick (a lot thicker than the actual board). With L shaped fingers the bottom of the gl
