Hi,

I'm looking for an equipment to check on all the chip and ic placement pressure. Pls advise where can i find this type of equipment.

Thanks.

Hi Eric- Something I have been thining about trying are Pressurex indicators. Just type in Pressurex to get the info. http://www.sensorprod.com/pressurex.html Has a data sheet available for down load. I have not used this method/Theory but would like to know the results if you do so.

Enjoy, Cal

Placement pressure can be checked by using load cells. Both PCP and Entran make them and the amplifiers. They can be contacted at the following websites.

Eric,

You should be able to monitor the pressure of your nozzles by selecting: Diagnostics / Vacume check, depending on the type of machine you are running. When you cover the end of the nozzle, you should get a reading of about 500. This means it is working fine.

Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by step until it reach the PCB, after that put the paper by the paper out and check is the tight or loss. Different paper thickness with give the reading of thr pressure. Hope this can help some study point for you.

Regards, Hun
