What is CFM? Look here: * http://bugclub.org/beginners/processors/cfm.html * http://users.aol.com/jackproot/met/spvolas.html How do you measure CFM? Look here: http://www.orionfans.com/html/air_flow.html Anemometers are used to measure air vel

The right way is to know what velocity numbers would net you the required flow for your oven and then measure with a manometer. The required velocity is primarily a function of pipe diameter (and blower rpms) but length and how bendy it is contribute

Hi We are in the process of developing a lead free product to be used in a non lead free selective soldering machine, i do have concern in these, and hope you guy can share your experienced expert opinion: 1. What does it take to convert to lead fre

So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

right, so for the main one, we will operate it in between it, and the tables against the wall. We plan on adding SPI/AOI to the main line, with the oven staying put, and the rest shifting downward. Question: 1) Landlord wants fewest holes in the r

James, Could it be the convection in the reflow oven itself.Maybe somebody has increased the air flow or convection rate. I have seen an issue with an sot23 blowing off pad in a BTU paragon due to air flow in air curtains being too high. Hope this h

Is it the pressurized system or the pump system you have fitted to the machine? Are you getting an error message 'No flow nozzle 1'? Check the 'ShoRate' gauge at the back of the machine and make sure the ball bearing rises in the glass tube when you

This is basically the reply that I had from Heller ovens regading this - "The recommended air flow is at the back of the machine near the vent. From the book I copied from you it should be 500 CFM. If you do not achieve this figure, it not a great

We bought a used Parker Balston Nitroflow 60 which has an integral scroll compressor. We're not familiar with the machine so hoping someone here might be. I am trying to figure a few things out: 1. When the compressor turns off from reaching pressur

Find out if you can separate the dehumidifier controls from the heating/cooling controls, without adding an air handler. Otherwise I think you'd need to add a dehumidifier that runs independantly. Don't forget that system capacity has to be rated fo
