Analysis Defect Non-Wetting U7 on PCBA Model DM3XX
(Politeknik Negeri Batam, 2023-07-11) Nasution, Adnan Octaridho; Asaad, Nur Sakinah; Octowinandi, Vivin; Muhammad Arifin
The DM3XX production process, non-Wetting rejects were found. The most difficult aspect of any solder defect on area array package is inability to observe defect easily. It's important to understand the characteristics of solder defects to identify appropriate actions to reduce defects in soldering process. Head-in-pillow defects are solder defects in area array packages characterized by a lack of coalescence between the solders. The purpose of this study was to determine causes of Non-Wetting U7 IC (CG201-10022-1R00) DM3XX and to prevent occurrence of Non-Wetting U7 IC DM3XX. To find out causal factors and prevent occurrence of U7 IC Non-Wetting, a fishbone diagram approach and mapping process are needed in this study. After analysis using fishbone diagram and why why analysis, defect non-Wetting caused by bent U7 leads, resulting in uneven soldering in reflow process. The bent position of U7 leads can't be corrected in other SMT processes. It can only be prevented using AOI. The AOI value required in non-wetting to process assembly is at level 70 for lower and 70 upper spec checking. Both factors have contributed to the decrease in reject produced by the process. Has an influence of 98.92% so it will be effective when implemented.
Cycle Time Improvement for Soldering Process on the Assembly Process of RFID Card

Teaching Factory Manufacturing of Electronics (TFME) is facility of Politeknik Negeri Batam that designed according to the real industry orientation in Batam. TFME already had mass producing RFID Card for student ID card Politeknik Negeri Batam with production output is 400 units per week. Several items need to be considered during mass production which is quality, quantity (output) and production costs. Profit will be achieved when we produced unit with high output and low cost. Based on the analysis and collecting data showing that Soldering Antenna on the assembly of RFID Card is the bottle neck process with high of cycle time consuming 180 sec/unit.
Improvement Tools and Parameter on Coating Manual Machine for Coating Automatic Machine to Reduce Reject
(Politeknik Negeri Batam, 2023-07-10) Aldi Wardana, Yoga Dwi; Asaad, Nur Sakinah; Budiana; Ridwan
NTC (Negative temperature Coefficient) is an electronic component, esistance value changes based on temperature changes and this component is a passive component. Manual coating machine is a machine for coating or wraping NTC (Negative Temperature Coefficient) material. Improvement automation on this machine is for updates machines previously operate by manually become full control by a compute. Manual machine can’t monitor reject and performance machine, because of that author make an improvement on this machine to reduce reject, optimal method, monitoring performance and other. Method using on this proposal is update parameter and make a machine become automatic with new tools like a using motor stepper, pneumatis system, and vibration system. Update parameter doing by study of parameter for best parameter to get more stable quality, for tools define by spect material and spesification part. This proposal expected can make a quality stable, reduce the reject, auto operate and movement machine more optimal. The target for reducing reject make a 0.78% from the target 2%, for consumption of chemical a and chemical b reduce until 48.57% from the target 30%, for OEE on auto coating machine get 88% from the target 85% and cycle time on 1 hour get 4031 pcs on manual caoting machine make a 5379 pcs on auto coating machine for percentage can reduce until 33,44%.
Inspection of Clevis

An IPQC inspector is an officer who controls the quality of a product or material. IPQC's role in maintaining the quality of a product gives customers a sense of calm. Therefore, it is necessary to do an analysis to improve the quality and quantity of production. Therefore, it is necessary to collect data and review things that can improve the quality of products or materials. Therefore, it is necessary to collect data both in hardcopy and softcopy to see the development of the quality of the products produced by operators. At this time the use of clevis has been widely used starting from construction machinery, trucks, trailers, and as well as aviation systems. Therefore, it is necessary to implement a checking system that can ensure the safety level of the clevis. The thing that often happens when I encounter rejects on clevis is rejects on the gate clevis and pin holes, which are the two things that support and bind the clevis.
