CERN Erik van der BijTS-DEM Turn-around time Prototype electronics production multi-layer PCB, standard priority Tight planning and follow-up needed Need companies that you can rely on Queue 2-3 weeks Layout 1-2 weeks Layout (and queue) 4 weeks PCB fabrication 3 weeks Assembly 2 weeks Margin 1 week We do these steps for over 2000 projects per year

CERN Erik van der BijTS-DEM Supply contracts Printed circuit boards –300 KCHF/year, increases to 400 KCHF (LHC production) –Have 4 contracts (Italy, Belgium, France, Norway) –difficult to balance (60%, 15%, 15% and 10%) as one is much cheaper => next time only two companies Front-panels and small mechanics –150 KCHF/year –distributed over 2 companies (Spain, France) –has a local stock of half-products (from Stores) –Call for Tender came up with 3 interesting companies (ESP, FR, S), try them all out for three months (blanket order) before deciding to make a contract with only 2. Pay some attention to small contracts –you can save on a single Xerox copier 1500 CHF/year
8
CERN Erik van der BijTS-DEM Service contracts Design office (S081-> FSU-03) –11 people (9 designers + 2 for documentation, ordering and billing) –per year: 500 new designs, 150 modifications, 150 production only –1. Client sees first Section Leader about planning and technical solution 2. Section leader plans during weekly meeting with Team Leader Fabrication of Printed circuit boards (S081-> FSU-04) –10-11 people –around 1000 jobs per year –Client sees first Section Leader for complicated projects; for simple projects client goes directly to Team leader
9
CERN Erik van der BijTS-DEM Service contracts Assembly (S081-> FSU-03) –3 people. Part of FSU of design office –around 200 prototype jobs per year –Client sees first Section Leader for complicated projects; for simple projects client goes directly to Team leader –larger jobs done on premises of contractor
10
CERN Erik van der BijTS-DEM The good and bad of service contracts A good way to stay competitive –keeps us and the contractor sharp (DEM has real prices, no mix w staff) Flexibility in size –can add or remove people with low effort and within a short time Contractor does not have knowledge in our domains –it’s only the Team at CERN Skills not updated –hardly any formal training given To keep clear separation staff/IS, cannot use IS for CERN core technologies, responsability for software and hardware, research on working methods and new programs, contacts with companies, reception of clients during absence of section leader + + _ _
11
CERN Erik van der BijTS-DEM FSU should improve some things Extra layer of management –Team leader has now a manager local at CERN –IS personnel will feel more part of their own company Contract for 5+1+1 years instead of 3+1+1 –a change of contract is always difficult However: price increase –extra layer of management –Swiss contract instead of French
12
CERN Erik van der BijTS-DEM Ingredients for success Keep CERN core technologies with CERN staff –manufacturing of high-density circuits in cleanroom –SMD assembly of prototypes (<10 pieces) –still it would be a disaster if full change of IS personnel happens Don’t mix CERN staff and contract personnel CERN staff should be first interface to client –planning & decisions where and how work should be done –technical discussions directly between client and industrial support
