Low cost SMD Oven for making SMD samples and Prototypes
This SMD Oven Controller (SMDOC-01) is designed to use with a toaster
oven. It provide a low cost solution for making SMD prototypes and samples. The temperature profile is similar to the expensive industrial SMD oven provided. So, the sample quality is as good as the industrial oven can do. It is capable for packages including 0402, BGA, QFP, SOP, SSOP, TSSOP, SOT, etc. It is an indispensable tool for R&D and making samples. It is very suitable for electronic companies, laboratories, universities and hobbyists. SMD Oven Controller (SMDOC-01) is only US$206, including oven (PCB size is large up to 19 x 17cm) is US$283. Voltage 220V, 8A fused. Features: 1.Small, low price, performance comparable to expensive industrial SMD oven. 2.Capable for any SMD packages. An indispensable tool for R&D, sample making and small batch production. 3.No hand soldering. No painful. No difficult. Save time. 4.Connectable to PC via RS232 for profile setup and temperature monitor. It can also operate independently without PC. 5.Simple to use. LEDs indication for each stage of pre-heat, soak, reflow and cooling. Alarm and power cut off after finished.

Low cost SMD Oven for making SMD samples and Prototypes
There's a much simpler and cheaper solution for experimenter 'one- off'
board soldering. Just solder all the part leads to the board without worrying about solder bridging. After you're done, come back and wick off all the excess solder with solder-wick. This will remove all solder bridging, but will leave a good strong solder joint between the part leads and the board pads. Of course it only works on parts with exposed leads, not BGA's etc. Joe W3JDR "erica" wrote in message ups.com... This SMD Oven Controller (SMDOC-01) is designed to use with a toaster oven.

^^^^^^^^^^^^ This is something of a show-stopper for those of us in the US... ======================= With 117 V being the normal nominal domestic voltage , I believe many premises in the US have nominal 234 V outlets as well , hence 220V wouldn't be a problem.........let alone be a 'show stopper' Frank GM0CSZ / KN6WH |

Both are big (like 30+ amp) connectors. So, yes, it is a problem. |

Not true at all!
220V outlets are very rare in residences - no need for them as 220V is only used for very high power equipment. The exceptions would be central air conditioners, electric stoves, electric water heaters, but these are typically hard-wired in a junction box. Run-of-the-mill appliances using up to about 20 amps are usually run on 110VAC Joe W3JDR "Highland Ham" wrote in message ...

Or would such an outlet be available anyway in relatively new houses ,built after say 199x ? Just 2 questions . Frank GM0CSZ / KN6WH |

ALL us homes have 220 brought to the fuse / breaker box. It is a 220 volt, center tapped transformer on the pole and all three lines are brought to the breaker box. . Each half of this winding supplies the 120, 110, 117, whatever you choose to call it. Half of the circuits in your home come from one of the winding ends (phase) and the center tap is connected to the common; the other half come from the other "phase".. Therefore you have two phases of 120 and they are 180 degrees apart. Some call it single phase, I think it should be called two phase...cuz it is. (:-) If you really need to get 220 quickly and easily [ and do not draw more than than the 15 or 20 amps of your brealers] you can find two outlets on the two phases and get one half of the 220 from each. I did this for a visiting relative from Germany so he could run his electric shaver. It is still the talk of the relatives... Since I built my house and did the wiring with Dad's help, I kept a drawing of all the circuits, I knew that I already had two phases in the guest room. A couple of cheap extension cords was all it took, with one blade of a "three prong adaprer" inserted into each hot side of each extension. Guest 220 in 5 minutes! I'd feel ok drawing 8A this way, but you shouldn't try this at home...I'm a professional. (:-) Linears should have either 1- both 110 and 220 internal wiring options, or 2- just 220 But 120 is is a real stretch. 73, Steve, K9DCI |

Assuming a 67 percent efficiency (am I too pessimistic?) a legal RF power amp would need 1.5*1500 = 2250 W (say overall maximum of 2400W) which at 220 V means 12 Amperes. So, a shack without 220 -234 V power supply would need a dedicated supply from the switchboard . Here in the UK we do have 115V industrial power tools,which need to be used with a 230/115V (usually portable) safety transformer with the secondary having an earthed centre tap ,such that in the event of a 'fault' personnel is exposed to a (peak) voltage not exceeding 1.4*58 = 81V which is considered sufficiently low to prevent electrocution. The nominal domestic supply voltage within EU countries has now been 'normalised' to 230V ,meaning that (within a voltage band) the same equipment can be used in all the countries. Before , the UK had 240V and continental countries 220V . This often meant that for example an (clothing) iron for 220 V had a very limited life when used in Britain . The voltage at my place (rural area) is nowadays usually 236-237 V ,whereas earlier it was up to 250 V or sometimes even higher. Frank GM0CSZ / KN6WH |

Frank GM0CSZ / KN6WH In the cell phone base business, everything (almost) runs off battery systems. There were two cases where Development Engineers not knowing about our mains system, where developing products never before run off the mains. In one, the presence of "both" 120 and 240 was causing some spike absorbers, designed for 120 systems, to pop from the 240. The other was a small base station which had its power input connections designed by Mechanical engineers. It came to my test group without the power cord connected to the black (protorype) "barrier terminal strip". One of the Develpoment Engineers called another for the connections and made them. It was plugged in, but wouldn't work. Several Engineers started checking and discuvered that the serial port on the control laptop had been fried. Several of us put our noses to the connector and could smell the burned components on the unit. We also noticed that the heat sink wasn't getting warm. I and several Engineers put our hands on the case to test this. Note: In the US, we have a third wire in all outlets which, though it is the same as the common or neutral (basically also ground or no potential) side, it is used to connect to any exposed metal parts. The purpose it to divert any hahazzardous shorts to ground and blow a breaker or fuse rather than harming someone. We were focused on finding the cause. Several of us worked trying to analyxe the failure and found the serial interface of the unit has fried as well as the lap top serial port. Findings: The HOT of the 120 ( instead of the safety ground connection) was connected to the chassis. This placed the outside of the (as yet unpainted) housing at 120 VAC relative to all other grounded equipment in the room! I was one of several who put his nose up to that hole to smell burnt comopnents. I was one who felt the unit for heat build up. It hit me half way home. Needledd to say, I gave the Mechanical and Electrical Engineers a lecture on mains principles. 73, Steve, K9DCI |

Using two outlets without some logic to make sure both plugs are connected is a very dangerous setup. The simplest setup is three relays, two to detect the 120 VAC on each cord that together energize the 240 VAC outlet. -- Service to my country?

I'd blame the engineering manager who let mechanical engineers design an electrical interface, and then apparently didn't design-review it. Joe W3JDR "Steve N." wrote in message ...
