The paste dispensers work well as long as the humidity in your shop is properly controlled. If it gets too humid, and the paste gets "soupy", then it will take less air pressure to dispense it onto the stencil. Paste dispensers use a controlled, pre-

Hi, I know for sure that by controlling temp. and humidity conditions in SMT assy lines room, one gets advantage in screen printing, adhesive dispensing, and pick&place machines mainteinance. Does any one have any advice on why else is a clean room

We are starting up an SMT line with a printer and convection oven.... The area we are considering for the printer is totally uncontrolled for humidity, temperature and even cleanliness. We are working on the filters to keep particulates down, but I

For me, it would depend on a couple of things: 1. How many parts are stored in this manner on a regular basis? 2. Was the oven used for anything else other than this type of storage? If it was a low volume of parts, and the oven wasn't used for

HI, we use the SMT Tower software to controll it. The Tower is afully automated storage which controlls the humidity. Is a component leaving the Tower, the time is runnig. Is the Component back in the Tower, the time is stopped.

Solder balls or mid chip beads? Remember IPC classification for Class 2 allows mid chip beads encapsulated in flux. Usually on R's and C's first thing I would do is verify .006 laser stencil 10% reduction and the most critical, The paste must be on t

Good morning, I got a question regarding Immersion Silver Board Finish. It has been imposed on us by our customer that we must manufacture PCB through the SMT process within 24 hours of breaking the seal on a bag of PCB containing Immersion Silver.

Thanks to all for their inputs. @Hexielectronics, I am now trying to assemble the board by attaching it to a frame and removing the frame while waving it. I plan to put the boards back on the frame after the board cools down. Could you explain more

Hi, I am new in this industrial. I learnt that PCB may absorb moisture and eventually caused delaminate after heat apply on it (reflow or wave). But I don't quite understand, if the PCB was keep in sealed bubble bag, and with the humidity control wit
