Hi, It depends of your boards(are they for SMD or not) and how many boards you assemble. The process at all is like that: 1.Stencil printer - to adjust the paste 2. Pick and place machine(for your quantity) 3.Reflow oven Theese are the machines you

Dear Sir, We are manufacturing Computer Motherboards & Networking products (which are having 2 to 3 BGA Chips onboard) in our plant. we are having 2 nos of HELLER 1800W model Reflow Ovens. this model reflow oven is having 9 heating zones at both top

I have been looking into buying a rework station like ERSA or PDR. What I am questioning is how well will these systems reflow BGA's with metal top/cover that are reflective. In addition, when preheating the board would dark body packages absorb te

I can help you, if define what type of components you used: Thru hole(axial,radial, pin insertion etc..) axial: milimetrics or standar(span of .200" or .350" ) radial 2.5mm , 5mm or 7.5 mm SMT (chip shooter(1206,0805,0603 ,sot 23 etc or more small

Pascal: Two elementary cautines are: 1 Don't dump the board before the reflowed solder is cooled. 2 Try to manage the side to side temperature variations in your oven. I wouldn't be surprised to see 5�C variation. Good luck

I suggest tow more ways: 1. try to differ the temperaturte between top and bottom side duering the reflow process. 2. try to add some glue dots under the falling parts befor the placement/reflow process Good luck Michael

I have recently encountered a new pcb design with a very high density of components on either side of the pcb. One of the suggested "fixes" is to use the smt pads as vias i.e. the via will be drilled thorough the centre of the smt pad. My concern i
