Yes, using an illuminated magnifing glass helps. How well your board fixuring is on the table will effect print alignment on other boards loaded. 0.5mm & 0.4mm will require very good fixuring, like you can get with tooling pins if the board has non-p

Unplug the tactile sensor and check the switch with an ohm meter. If the tactile sensor switch is good go in one of the drawers in the back of the machine and with the help of your schematics find the opto-module that controls the tactile sensor circ

Sounds to me like the driver for the tactile is not working. The tactile has three components to it. The first is the switch, the second is the pneumatic up/down actuator and the third is a small motor in the tactile assembly. The motor has a driv

Debi, Both machines are good and will do a great job for you on Rigid as well flex circuits.Every Mfr.will come to your site and give you a piece of equipment on loan to try for a month hoping you'll buy from them.Why don't you arrange that little ex

You are correct in understanding that the vision system comes into play for subsequent boards- to align them. Yes- if you missalign the first board and set the cameras to that board, all subsequet boards will not be aligned. Mylar is a thin polyester

SPM is superior. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the UltraPrint 100. UP100 is microprocessor controlled while the SPM has a PC. The SPM cameras can be positioned more rapidly and with greater accuracy than UP100's.

Best recommendation is to compare the two machines with your boards and stencils. Either vendor should be able to arrange for a �test drive� at one of their demonstration facilities or at a local friendly customer. I�m afraid that your request for �o

The MicroFlex is not really new. Its the UltraPrint 100 re-engineered and improved. UltraPrint 100 / SMTech 100 has been around for many years. I don't believe the DEK 248 offers a Stencil Wiper option. I worked on MicroFlex machines. Vision system i

SPM is superior in terms of technology and application. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the MicroFlex. MicroFlex is microprocessor controlled while the SPM has a PC. SPM can print down to 12mil (0.3mm) fine pitch no

You should be able to get a one-print Mylar frame for the SMTech 90 machine from SigmaPrint, http://www.sigmaprint.co.uk Yes, with vision you store images of two features such as solder lands or fidicial marks from opposite corners of the board. With
