I have a large monoblock ceramic filter on a PTFE based pcb material. The filter has a metal casing soldered onto the ceramic filter. I am concerned that if the heating rate is to rapid, then thermal shock / differential expansion could cause the fil

What does the technical data sheet for the component recommend for reflow profile ? Can you post a photo of the component ?

| 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

PCB is 12.25" x 4". There are large MOSFETS on the board. Two large Electrolytic Caps. Two Large Multi-Layer Ceramic Caps. 15 C Size Tantalym Caps. A fair number of IC's, (SO-8's, SO-16's). No BGA's or finepitch of any kind. The board is double sided

| 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

Does the flickering go away once the oven reaches its set temperature? It will draw a lot more current while its warming up then when its running. Are your lights running on one leg of the same 415 VAC circuit? Reflow ovens are mostly resistive loa

I solder a lot of differnt products throught a Reflow oven that are non PCB baised Axial leaded components typicaly, mounted vertically in jigs. where i can for cost reasons I use aluminium jigs but you have to experiment with the thermal mass and de
