“ DESIGN OF A MASTER MAINTENANCE PLAN FOR 6 EQUIPMENT AT KIMBALL ELECTRONICS MEXICO S.A DE C.V” August 2018 Reynosa, Tamaulipas Alfredo Alejandro Chávez Vázquez

The Project is designed at Kimball Electronics S.A de C.V Address: Av Mike Allen Av. 1145, Industrial Reynosa, Reynosa, Tamps. Tel: COMPANY This company designs and manufactures printed circuit boards for different industries: Automotive, medical, industrial and public safety.

EQUIPMENT ERSA VERSAFLOW 3/45 Criticality Level: High Risk This equipment welds pins of the electronic boards (PCB) APOLLO SEIKO Criticality Level: Medium Risk This equipment welds pins of the electronic boards (But this machine produces less product)

EQUIPMENT ROUTER CENCORP Criticality Level: Medium Risk This equipment cut electronic boards according to the model to prepare them for the next process. PVA Criticality Level: High Risk This equipment puts a conformal coating on the PCB

EQUIPMENT AOI Criticality Level: Medium Risk This equipment inspects the material after welding process to verify and ensure the good quality in the welding. JADE Criticality Level: Medium Risk This equipment welds pins of the PCB (But in more time)

MISSION AND VISION OF THE MAINTENANCE DEPARTMENT MISSION To eliminate the unnecessary costs generated by inappropriate maintenances, decrease the number of fails, increase the availability of the equipment and to improve the stability of the productive process. VISION. To be the best department in the company providing high quality maintenances according to the standards that we have.

STRATEGY PLAN MAINTENANCE

MAINTENANCE INDICATORS The Maintenance indicators that are used in the company are mainly two the OEE and the Yield both are used to establish the number and level of fails also the production in all the equipment with different graphics.

MAINTENANCE INDICATORS OEE Availability = Run Time / Planned Production Time Performance = (Ideal Cycle Time × Total Count) / Run Time Quality = Total Count – Defects/Total Count OEE = Availability × Performance × Quality

STRATEGY TO INCREASE THE OVERALL EQUIPMENT EFFICIENCY (AVAILABILITY)

1Photo 2 ERSA VERSAFLOW 3/45 3 Serial number: SO-11B-17D Brand: ERSA 5Model: VERSAFLOW 3/45 6Company´s identification number(UMH-PRO-01): Voltage: v 8Amperage: 102 A 9Fases: 3 10Potency: 68 kW 11 Purchase date: May Waranty (expiration date): 18 August Manufacturing date: April Width: 1.7 meters 15Length: 5 meters 16 Height:2.25 meters 17Technical specifications:It Works with coordenates that need to be exact.

18 Technical specifications 2: It Works with 0.7 of nitrogen pressure 19 Technical specifications 3: It Works with two preheaters with a temperature of 240 C 20 Technical specifications 4: It Welds with SAC 305 soldadure 21 Technical specifications 5: It Works with two types of flux 265 and R800 22Equipment Function. It is used on the welding process to Weld the pins of the electronic boards 23Systems: por ejemplo: It has pneumatic, electrical and mechanic system 24Department/área/ Productin Line: It is used on the welding engineering process 25Transportation Requeriments: Is necessary a lift truck for the correct transportation 26Installation Requerimients: Needs electrical, air and nitrogen sources 27Special Requerimients:The conveyor needs to be exactly adjusted for the pallets 28Recommendations: Don,t turn of the machine with the button only use the stand by 29 Hazardous wastes: The dross from the pot is treated according to the hazardous paper on the machine, is necessary to put the dross on the recuperation área. Supplier name: Mashine gegeben (German supplier) 30 Supplier data: NA 31 Address: Wertheim, Germany 32Telephone:NA 33 NA 34Contact: NA

THE MOST CRITICAL EQUIPMENT This equipment is considered as critical because if this equipment fails the line stops and at the same time the production stops. It affects all the processes that continues after the selective machine. Machine/EquipmentCode Selective Machine ERSA Versaflow 3/ TaskFrecuency Change the type of flux. First we need to close all the valves and after that we need to despise, finally we need to purge all the old flux later we need to clean it with alcohol and finally to fill the tank with the new flux. NA Tools/Materials Gloves, glasses, alcohol,cloth. In case of a power blackout we need to tun off the machine with the contact breaker and when the energy backs we need to verify that the machine Works correctly. NA Tools/Materials Gloves, security glasses. In case of a preheater’s resistance fails we need to change it for a new one, but first of all we need to wait until the temperature decreases, and when is cold we can change it. NA Tools/Materials High temperatura gloves, glasses, cloth.
