More zones = higher thruput. Is it better to have (8) 12 inch zones vs. (7) 15 inch zones? One thought might be more parts = more cost = more potential for failure. I have a bunch of BTU's with over 12,000 heating hours of combined opertion. I

I managed to find a brand new old stock Novastar GF-12 oven for $250 (it was used once but you can't tell): https://milwaukee.craigslist.org/tls/6539855333.html This seems like it may be perfect for my needs. It does seem industrial grade but only

| | I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the a

A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Correct preheating of the assembly is critical. Check with your flux manufacturer regarding the recommended topside pcb temperature as it enters the first wave. It is important that this temperature be achieved without burning the flux on the bottom

I would use a foam fluxer since spraying rosin will make the stickiest nastiest mess you can imagine. 18 layer board huh? You will want convection preheat, both top and bottom preheaters, preheat tunnel of at least 4-5', a chip wave, laminar flow w

I am having problems achieving correct pre-heater temperatures with our Hollis solder wave. Our original "Verification Golden board" program uses a conveyor speed of 5ft per minute and pre-heat temps of 300, 350, 400 respectively. Our "golden Board"
