Does anyone know of a supplier of ceramic reflow Thermodes for a Microjoin 4200 hot bar machine? Microjoin was acquired by Miyachi Unitek and they of course do not support this machine any more.

Hi iv40 Try with NIC ceramic capacitor that was tested in wet process. We hav succeed with these cap after we found some failure with Kemet ceramic Cap which tested in dry test process while manufacturing.

Steve, Depending on the type of equipment you are using for P&P you may want to consider placing and processing the substrates in Auer boats. I have provided many applications for ceramic substarate users using purchased Auer boats or machined palle

Suggest you ask vendor for a failure analysis. Ceramic chips have specific signatures for mechanical or thermal shock cracking. The vast majority of failures are due to mechanical flex. Depanelization and secondary operations such as hand insertion

We have used scribed ceramic from CoorsTek for many years with no problem. You will have to control your scribe depth so not to break it during processing. If you have any more question you can e-mail me.

Hi We are experiencing serious problem with ceramic capacitors. They are with low electrical resistence and the problem is intermittent. We found some of them with micro cracks but not all. What could be the causes for this problem? We are su

Most of the time, Ceramic cracks are cracked due to mechanical stress. Check your depaneling methods. Cermaic caps that are close and perpendicular to the board edge are especially susceptible.

Try heating a blank board on a hotplate to 183 deg C. with a board this thick, if the layer construction is poorly balanced, it may bend enough in the region of the ceramic capacitor for the soldered joints to crack it on cooling to ambient.
