We running small quantity board and frequently do conversion. we produce very simple board no BGA only resistor, capacitor, LED, IC and transistor. We are running same model top and bottom in 1 reflow oven. could i use top profile when reflow bottom? Since our program temperature setting for top and bottom same. Kindly please advise...

I am thinking about using them and would like to know how there quality and service is. Also how are there prices? Would you consider them competitive in the market place? Any feedback would be great.

The PC screen also got very noisy. We replaced the power supply with a used replacement and the machine initialized fine the day before; we came back this morning to run it and when we powered it up the same thing happened. We checked the AC into the power supply and it is 208V. There is no DC output from any of the channels on the power supply. Has anyone seen this before? We're quoting new multi-output supplies, and we're also considering independent DIN power supplies of sufficient wattage but we're not sure how that might go either. Thu, 01 Dec 2016 13:35:21 GMT Selective Solder Program Transfer http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18684 My company purchased a preowned EBSO SPA 400-F selective solder machine awhile back. I have been trying to transfer a program I made using the EBSO offline editor, but I cannot seem to communicate with the machine using my desktop. I have a serial cable running from the desktop to the serial 'com' port of the selective solder (the com port on the lower right, on the outside). I've tested the com port on the computer to make sure it actually works and it does. So first I start up the selective solder and use the touch panel on the EBSO to select the transfer option on the loader menu. Then it says 'connecting to host...' with a progress bar which doesn't move. On the desktop I do have the software open with the program I made. I clicked on Edit > Program and then the send button which brings me to a blank screen which I assume shows a log of what it is sending. It is blank however. I am wondering if there is something I am missing that needs to be done to transfer the program over. Anyone have any experience doing this, or a reason why it is not transferring? Thu, 01 Dec 2016 10:40:51 GMT Keeping Blue dry during wash http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19192 Is there some material that can be applied to a bluetooth module to keep wash water out. We need to clean the board, however, this part is not washable. We are running a NC process. Any Ideas?

We currently have a Universal GSM (circa 2004) GI-14 and we are approaching software limitations on multi-pitch BGAs. Any additional information about the SM421 capabilities and limitations would be appreciated. Thu, 01 Dec 2016 08:03:38 GMT Switching to SN100C wave solder pot http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19198 Hello, I am new to this forum, and was hoping to get some advice/information from those of you that have switched your wave soldering machine to SN100C. I have read some old threads about people having great success with SN100C. My question is- what are your thoughts now after using it for many years? How quickly did the SN100C attack your stainless pots? Any insight as we begin this transition to SN100C in our wave soldering application?

We have a couple of these and it looks like both have lost the code for some reason (powered down for months with no battery). I contacted UIC a while ago but haven't had any reply to my email. Sun, 27 Nov 2016 05:07:15 GMT temperature profile for ENIG http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19203 Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence on thermal characteristic of reflow, what should be the temperature in reflow stage? I found some formula, where is the melting temperature of solder + 20°C. In case of lead free it will be 228 + 20 = 248°C. I have temperature profile with maximum 235°C. In one minute it is going from 218°C to 235°C and decrease to 218°C. Then it is in cooling phase. On panel with ENIG we have issue with wrong soldering, respectively with bad wetting. I made some pads with handle solder and the result is OK. The nickel is cca 3,7 um and Au is 0,05 um thick. Sat, 26 Nov 2016 00:56:17 GMT PCB to Control Automotive Relays http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19204 So, project background first. I am in the process of designing a PCB that incorporates a microcontroller, LEDs, capacitive sensors and relays to control auxiliary light in my truck. I have the little stuff worked out and have it prototyped and working, but I want some outside input on the relays on the board. The relays are 30/40A Bosch Style (5 pin) automotive relays. They are triggered by the microcontroller when it receives a certain input. I want to make sure that I have adequate trace widths to support the relays when an auxiliary component is triggered. Right now I plan to use 1 oz copper for the board when I have it printed (trace width is 150 mil on the relays and power). I have attached the PCB design to this post. Each individual relay would have a max of 30A @ 12V on it, and all power lines on the board are fuse protected. In all reality, it is likely that only one relay would be on at a time, and only a single relay will need to support the 30A load, the other relays will only need to handle a couple of amps. I am new to incorporating microcontrollers and higher amp 12v loads in to a PCB, so I may be approaching this completely wrong. Any input is greatly appreciated! Fri, 25 Nov 2016 20:54:58 GMT
