What does acrinym---BNY mean? can't you use Paste In Hole process,if the pitch is large enough?You can find imformation about PIH everywhere. we have tried PIH,selective soldering,wave soldering,and found that wave soldering get the best solder joint

Need more information. BUT if your strictly considering just the paste change. I would imagine your changeover would be little to no different than changing to the second board if you were using the same paste. Maybe take extra care cleaning your sq

jng123, Process-wise using one solder paste type is preferred regardless of paste type. If you want clean both paste types in one cleaning machine your manufacturer might have, this potentially could lead to white residue issue due to chemical reac

Hi ! The main problem being faced currently is formation of solder balls - to be precise, these are micro solder beads generally found attached with bodies of SOTs, Chip Caps, Chip Resistors, between pins of SOICs (50 mil) - lying on PCB surface,

Hi, We have a SMT production like, however we have very little experience with through hole assembly. We design everything to be completly SMT based, however connectors are the only part of our product that still requires through hole assembly. Cur

Dear Fastek. For the Front panel board we are using multible ( 4 boards in one PCB. even thought the balance between the DEK printer and the placers still big 6 sec as a difference. But, may be this is a good idea for the main board? may be also it's

Dear all. We SMT line based on unversal machine and we are using DEK machine for printing with the two processes ( solder paste and glue ). I have seen that we waste time in Glue process using DEK machine because the machines are very quick than the

Dear Kanwaljit Singh, my opinion is following: 1)solderpaste type is ok - usual (alpha-metals has this problem inside the paste paste- holder problem) - what do the operator when production change -clean well the stencil holes!! no visible rest on

We are starting up an SMT line with a printer and convection oven.... The area we are considering for the printer is totally uncontrolled for humidity, temperature and even cleanliness. We are working on the filters to keep particulates down, but I
