Hi, I have never been able to find an acceptable dispense process for dispensing small dots of solder paste. I currently have an auger screw automated dispense system and can not accomplish 0.010" dot sizes. In addition, stencil printing is much m

Pete, I started with the App engineers, they had me try a 21g needle then a 23g needle then a 25g needle. The tech's are the ones suggesting that I slow the pump down to half speed and try a 27g needle. The needles are $150 a piece.....I now have

If you find the correct type of adhesive/needle size then dispensing certainly is no problem. With a footed needle a very repeatable process too. Much more flexible than stencil printing and no need to mess around with stencil cleaning. But with auge

We are using a GDM with a linear piston pump fitted to dispence adhesive on 0603's. Use Universal part number 43273801 needle with a 42346504 piston. The single needle dimentions are 0.010 ID, 0.028 OD, 0.005 stand off

It's a common problem. Try using a different needle diameter. Paste type||Suggested needle size II||21 or larger III||23 or larger IV||25 or larger V||27 or larger VI||30 or larger Additionally, improper clearance between the auger pump screw and t

Chalk this one up to semantics. Regardless of when you start pumping (do you use a needle with a foot? In that case the pump will run when the foot touches the board), your volume of epoxy is the same. You just have less room for it where there is si

hello- I am looking to add into my predominatly Fuji SMT lines a glue dispensing machine. I currently have for dispensing technology is a Camalot 3800 in one of my two lines. The second doesn't have any capability for glue , thus the reason for

| Earl, | | Srt makes a system called the summit 2100D. Its a relatively new product but it is designed for rework applications. The programming is simple and interfaces well with other srt products. As with any dispensing system, you have to cl

Most of the machine suppliers Fuji, Siemens, Universal and Panasonic did regret that they were building glue machines. Applying adhesive compared to placing a component looks so simple, but it is not and the defect rate is higher than placing 1206 c

Okay, I've read about the pros and cons about solder paste dispensing. Now, I have a Camalot 3800 and I want to experiment about dispensing solder paste. I have a needle gauge of 25GA, 23 and 22. My pcb components are; RC 0603-1812, Size B, C and D
