I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substrae)

| Couple of questions. | 1) Are we talking alumina substrates as the ceramic material? | 2) Are we co-firing gold as the conductors on the substrate surface? | 3) In other words, is this a hybrid thick film circuit? | 4) If so, how large or small? S

Hi Gents, I heard people having concernes by using 2512R SMD resistors due to potential solder joint reliability defect(CTE mismach among ceramic/alumina+solder+PCB) when soldered by lead free alloys (SAC like). Any experience/news about solder j

We have performed some EDS analysis and found high percent (approx 18% ) of Ni on surface of gold pad. Found Tungsten as well. This is an HTCC alumina package. Thickness of gold was confirmed and found to be in spec. We believe we are dealing wi

| We are taking enquiries for sub-contract work that we hope to be doing by Christmas. One of the enquiries is to assemble chip capacitors and an SO14 onto ceramic. Does the printing process, paste used and reflow process remain the same, or are ther

Hi, I'm having issues with boards sticking/jamming along the line, as well as what seems to be excessive wear along the guide rails. The boards are an Alumina Ceramic material and the rails differ by machine, but include anodized aluminum, steel, de
