Hi, We have a client requiring us to use a Vapor Phase Reflow Oven instead of our convection oven, the new PCB design will be ~9.3mm thick with some SMD & Pressfit connectors, does the PCB thick could be the cause of they requiring us the Vapor Phase

A bunch of thanks guys, we will take this in consideration. BTW, we will not go for the v-grove in the panel (2x8 boards + the extra cut of areas). The board house recommended us to go for braces/hinges, since this thin pcb-panel could easily break w

on the front end in design, minimize the pth connections to ground planes. this takes alot of work by the pcb designer and the approval of the design engineer. connect maximum of 4 ground planes to pth, minimum 1 plane. use spoked connections. ev

I'd start by checking and reteaching the nozzles (this is automatic, it'll measure the nozzle length and vacuum values for each nozzle). After that double check the value you have entered for the PCB thickness as this will impact where the machine t

Hi All, Need your suggestions on the below queries: 1. What will happen if the Au thickness maintained @ 0.5 to 1 micron (Where Ni Thick is within 3 to 5 microns) in 0.2mm Thickness FR4 PCB. 2. Is there any solder quality affcted during Reflow Solder

Hi mates, anyone done SMT process for micro-lead frame (flip-chip)before? Appreciate any process control caution points from the experienced guys (yonder the deep blue seas) who have done this product before. 1) pcb thickness 2) pitch-to-pitch (co

What type of P&P machine? Useing any Placement force? Ramp speed in reflow? PCB thickness properly defined? Tooling supports too high? Any doubble stacking of parts? Occuring with only one part manufacturer? Start with processes where problem is note

HI, just my 0,00001 cents Which preheat system does your wave solder has? for instance ? - IR ? - Bottom only ? - IR + Forced Air ? (bottom) - IR + Forced Air (bottom) IR top ? PCB thickness ? Appropriate preheat is important when looking to f

Thanks DWL, we have a board with double sided SMT components now. and there is an intrusive component on the bottom side which is build first. the connector pin is extending out by 0.3mm and this is causing printing issues when building top side. we
