I assume you using a fixed mass vapour phase system? Yes rates of rise are impacted by the mass of the PCB, larger the mass to mass of vapour phase the lower the rise generally. So if you load the machine with very little mass PCB rise times can be

A huge help in the very first statement, Josh. And yes, fixed vapor mass in the machine I am currently evaluating. OK, and a machine that can change the vapor volume based on a calculation of mass of the assembly sounds logical. (whirrrr,click... a

Thanks Pete B - great info. I am currently preparing a DOE to address concerns about reflow of componentry on the bottomside of the PCB while in the vapor. Specifically cosmetics and part dropping. Bottom side has no flux, but will be fully reflow

Hello, I am in the process of setting up processes for a low volume SMT line for internal prototype production, where a 500g jar of solder paste would last weeks. Our distributors only seem to want to supply 500g jars (anything else is significantl

First, you mix the paste in the jar with the centrifugal thing-a-ma-jig. Then what? So, how are you going to get the paste from the jar into the syringe [cartridge], anyhow? Are you going to use an Atlas Tool? How are you going to de-air the syri

I have an application I'm trying to solve which would allow me to vary voltage going to an Electric Solenoid at 24v ~3.0amps DC. What I want to do is create a device to vary the voltage going to the Solenoid using a pulsed digital input. I have a mot

I am having some problems getting the IP1 to place a SSOP28 package,pitch 0.65mm lead width 0.3mm. I am selecting computer vision 012 (tried 011) and vision type 100. EL data was put in looking at the datasheet and also measuring the device. Have tri

Hello mickd, 1) The EL data & Vision_type is NOT necessary when using MCS30 for IP1 machine. note : your input of the above might have cause confusion during VP, hence the OS error. 2) I would suggest the following... 2a) lower the Lead_check_are

HI Im new to this but i thought i would have a go at fixing my xbox 360 be re balling it,ive managed to remove the gpu and take all the old solder balls of and cleaned it up,then ive put it in a re balling jig with the 360 stencil fluxed the gpu wi
