Glenn: Greg's comments about Heller ovens are well taken. Heller sells more ovens than anyone. Beyond his and others general comments, you should be aware of concerns about buying used equipment. Suggestions are: 1 Check the temperatures of conc

Vishy, We have a project to study the impact of productivity lift in SMT lines using discrete event simulation tools (AutoMod is what we use). As Mr. Lahat found out, the high fidelity simulation of productivity lift is non-trivial. However, we have

Hello Yosef, non woven aramid reinforced pcb's are used where is a need for low CFT (coefficient of thermal expansion). Traditionally aramid pcb's were used in military applications in order to reduce the stress/failure rate of solder joints during

Rick, Does the ultrasonic cleaning system that you use reuse the same water for each cleaning cycle? I have had a similar problem in the past using a Brandson ultrasonic cleaner and water soluable flux. The problem was the buildup of flux in the clea

hello guys ; we are using a fine pitch component(0.65mm) on a thick copper PCB (Cu = 90�m) ; in this case we notice that we are in the process'limits , because the different supplier of the PCB are not able to ensure a good stability of it's process

I don't know what type of boards you are doing but if they are through hole or surface mount. You can get a whole line of used equiptment for pennys these days. I am sure that I could send you a quote for a complete line. The price of used equiptment

We are a small start up. We will be buying a stenciling machine and semi automated pick and place. ( We have the oven) We are presently stenciling without any assit and loading leadless parts only(no fine pitch) by hand. We need to improve thrupu

Clarissa, Like any used equipment, make sure both you and the dealer know what you expect from the machine. Ask questions! Make sure you understand what is involved in the refurbishment, if anything. Things like Technical support will be important if

At least!!! But we really can't have you throwing "your at least 1� worth." The rate for marginally useful information, disinformation, and compounded confusion has been set at 2�. When someone undercuts the market price for drivel, it hurts us a

Yins: We all use "Mnemonic" words or phrases to help in remembering facts. As part of our on-going training, we're trying to use a mnemonic to help people remember the resistor color code. Certainly, we "sailors" learned one that doesn't fit wit
