There are ledgitimate reasons for checking furnace calibrations, but let me clarify what that is. 1. TC's are not necessarily calibrted. Not unless you need "absolute" accuracy. TC's operate against a (non-linear) standard +/- a tolerance. Most

Please be careful about responses you get. Opinions run rampant and it is not wise to make a decision on equipment based on opinions of others. For example, you may get five negative replies on a piece of equipment from five incompetent idiots. Certa

Please clarify, Z axis gears (Blades)? The MPM head I believe is what your are asking is driven up and down via a lead screw. The machine gets the zero point from the "HAT" tactile sensor in the table nest. When squegees are installed the blades are

Ari, I would suggest you make a checklist of all your requirements (not just large scale production) and prioritize them with weights assigned to each. Fill in the checklist for each equipment and manufacturer and you'll have the results out. I wou

Do the math first. 10,000 boards a month means 440 boards a day (roughly, and not including weekends). Do you plan 2 shifts or only one? If one, you need to produce a board about every minute if you work an 8 hour shift. If all 110 parts are on on

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

I agree with previous postings regarding print speed: Solder paste type/versus fine pitch. Question: Is this a double sided pcb with fairly easy component packages on both sides? In such case, consider make the panel like this: Every second pcb in

We have a Vitronics mySelective machine (model 6749, or "the Fat Bastard" as we affectionately call it). It's configurable with various combinations of "select wave" and "multi wave" pots. Ours has one of each. The "select wave" is for the most pa

Hi, This is easy. If your just doing prototypes, then you could get by with a syringe of solder paste and a hear gun. You can put down a little solder paste on each page and then place the passives and heat gun the board. If you have other active p
