Yes thats always an awful site isnt it? It used to happen to use because an operator was opening the door during the cycle to check if it was done. I smartened up and fired the operator (for other stuff also) and put the washer on a pallet in a big y

Hi all, I need some one to give me a ballpark figure on yearly energy consumption of a reflow oven and a pick & place machine. I know it will vary greatly depending on various factors, but I just need some realistic figures. Say for a two shift oper

Wow, 90%? I've only been doing this 20 some years and never noticed! So buying an inspection machine gets rid of my defects? I should have bought one long ago! I don't think so. I won't even go into the lead free area.....

Hi, We run with two five zone ovens , so far we have managed fine. Like yoursleves , we are not under pressure for high thru put but I have no doubt this is something that we will have to look at in the future. What sort of settings do you have at

We are using VP on all of our lead free assemblies. 1. We are getting great, very repeatable results. 2. The profiles were created during the implementation of the equipment and we only change 3 parameters for each assembly processed. Heater power,

You answered your own question! Vapour phase is the way to go for this. Conventional ovens won't allow this, unless you find away to defy Physics. That's an absurd constraint to begin with: 200C. Most Sn-Pb profiles require 205 - 210 minimum for

If I read this right, it says 50 seconds or less above 200C. It doesn't say you cannot go above 200 C. Right? if so we do it all the time. We have some Quality gurus here that always blame our ovens for everything form a didle-I-Joe to a Dam-If-I

LISTEN this is quite a soar subject to me.i have old wounds too from these capacitators and argued with the darn engineers at my old place of employment that if they only stuck to wave and through � hoel stuff, they wouldn�t be in this pickle. IF the

A new fact is that some products that were ok a week ago are now no longer compliant. http://www.rsjtechnical.com/NewsDecaBDE.htm Deca_BDE is no longer exempted. How do you plan on finding out what products have it, so you can throw them out?
