Or simple logic. 1. You are only replacing the heat that is lost. (once the solder has been melted one time). 2. The hotter the pot the faster you lose heat. Are either of those statements not true? Don't forget if you are talking about power then

We did get the dewers of liquid nitrogen. They were something like $200.00 a refill plus a monthly rental. If you research nitrogen filters you will find a long list of disadvantages to the dewers. One that wasn't listed was a lot of times we would h

Grant, apart from troughput another thing to consider is boarddesign, If there is any SMD within a diameter (eg 3mm) of the connector you won't be able to solder them. I think those are the 2 main disadvantages of selective. That being said, for le

We now have an AOI in our process after printing and have noticed that all the small aperatures are getting clogged by solder paste. Mainly on all fine pitch parts. We are using Kester ws R562 SN63/PB37 mesh -325+500 90% metal. It was manufactu

Im sure you will get some better responses but here is a start. We went from UP2000 to UP3000 Ultraflex about 2 years ago. The UP-2000 uses tooling nests and UP-3000 Ultraflex does not. Makes a huge difference in setup time. Up-3000 is BIG. I think t

Hi all, We have an MCS30 connected to a CP6 and CP4 smt machines. Every time we need to set up a job, the operator has to type the data at the MCS30 terminal. We already have this data in a Windows PC file. I saw a ethernet and several unused serial

You may be JAX... My purchasing people send out for quotes from 8 to 12 different board manufactures from any where in the world. Each board mfger has different Laminate Sizes. So this makes things difficult. But wait, there's more. Now each boar

Thanks for the excellent info on testing uncured solder mask. I just checked with Chris Nash of the Indium Knowledge base and he told me that the Indium 3592 can be cleaned if need be and that I should contact Kyzen or Zestron (they are the 2 compan

I have the entire computer box assembly from a 1306/40 series machine. This was one of the first with the AC servo motors and digital drives. It was taken from a working CSM66 at the same time as I bought a CSM84. It was included to be used as spa

Hi, The problem seemed to be across multiple batches of boards, so I think they were made correctly, and we don't use a carrier in the reflow oven. However we just moved our equipment to the new factory yesterday, and connect and start turning on
