By "placement pressure" I assume you mean force. I don't know of placement machines that have transducers mounted on the placement spindles that actually measure force. We made a board with a force sensor mounted through a hole so that it was the sa

It read to .0001 and was repeatable to +/- .0005. As the SR coating got thicker, it was more sensitive to pressure since the transducer (ours was a 1/8" dia.) would press into the coating. You might request a demo from a vendor and see if it is a f

Here are some additional comments that have been posted on the CircuitNet web site: Fist, the answer is the same regardless of the specific paste type, (leaded or non-leaded). High pressure sprays should never be applied to a stencil. Stencils are

We have a MyData TP-9-2 with a in line Y wagon. It is a long screw and the vintage is 1994. The Y wagon vibrates at about 24 micrometers at about 25 hertz. Burnin reviels zero encoder pulse errors. Hystersis test indicates a Y axis Y wise varance of

A couple of things i would try: 1. Does function 30 give you a nozzle height that is repeatable. The number should be around 200.....+/- 20 or so. 2. I would change the z-rod because the spring could be worn out and when the vacuum turns on....it ca

Hi All, I'm having a problem with a Fuji GP-341. It has squeegee pressure control using a TEAC TD-320A comparator. I cannot get it to measure printing pressure. On the TD-320A it normally reads "2512" then flips to "oFl4" then back to "2512". If

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

There are three primary methods of stencil cleaning. � Hand Cleaning � Spray-In-Air Cleaning � Ultrasonic Cleaning Hand Cleaning: Hand cleaning involves the removal of solder paste or adhesives from stencils using a chemically saturated wipe and /
