OneDrive links are not accepted. Do not compress files using 7Zip.** - Emails are only accepted from the **MySeneca** email address. - Students need to send the following: - - **bottom-layer** - **top-layer \(if applicable\)** - **profile \(board outline\)** - **silkscreen-top** - **drill file** - **.FBRD** - When sending an email to the Seneca PCB Lab, follow the following email template: - Email Subject: Course Name/Lab Section, Student Name\(s\) - Email Body: - Course Name with Lab Section Do not include your Lecture Section \(e.g. ECP455NAB ❌, ECP455NAAL ✅\). - - - Assignment Name Some courses have multiple PCB assignments. Be specific: | **Course** | **Assignment** | | --- | --- | | CAD266 | CAD266 - Project | | CAD366 | CAD366 - Project | | DGS266 | DGS266 - Project | | ECP455 | ECP455 - Assignment | | | ECP455 - Project | | ECR255 | ECR255 - Project - Low Pass | | | ECR255 - Project - High Pass | | ECR353 | ECR353 - Project | | ELD255 | ELD255 - Project | | ETD555 | ETD555 - Project | | HSI255 | HSI255 - Project | | HSI266 | HSI266 - Assignment #1 | | | HSI266 - Assignment #2 | | | HSI266 - Project | | HSI355 | HSI355 - Project | | TPJ452 | TPJ452 - Project | | TPJ653 | TPJ653 - Project | | TPJ655 | TPJ655 - Project | | TRN553 | TRN553 - Project | - - - Instructor Name - Student Name\(s\) - Student ID\(s\) **⚠️ Requests without partner's Student ID will be rejected. Gather all information before sending the request.** A sample Email subject and body for 2 students working on a project is shown below: ![](https://students.senecapolytechnic.ca/attachment?file=%2FF0J7lN4eB1zL2Zj%2BizqlA%3D%3D) - The PCB Lab can't print text information contained in the design. Do not include text on the bottom or top layer. Projects with text in either layer will be returned to the student. - Students must use the PCB footprint efficiently. The board outline must be no more than 100 mils from any outer component \(see pictures below\). Projects not meeting this requirement will be returned to the student. In the picture below, the red border represents 100 mils. ![](https://students.senecapolytechnic.ca/attachment?file=jlPO9M6m6wCiJz%2FpUnjGEA%3D%3D) ![](https://students.senecapolytechnic.ca/attachment?file=2EgeOKGUHXahrTitaMmZUA%3D%3D) ## **More instructions on PCB guidelines are in the attachment at the bottom of this page.** - Every student project will be inspected for design errors. A design rule checking \(DRC\) process will run for each project to determine if the board meets the constraints set by the PCB machine. If DRC fails, the project will be returned to the student. The following guidelines will prevent DRC failure: - Trace Vias minimum diameter: 30 mils. - Pad Stack \(Annular Ring\) minimum value: drill hole value + 40 mils. - For the example below, a 40 mils drill hole will need a Pad Stack of 80 mils. ![](https://students.senecapolytechnic.ca/attachment?file=6ibvxstKk11zYcpfkFttJg%3D%3D) - Clearance minimum value: 14 mils. - ![](https://students.senecapolytechnic.ca/attachment?file=PgCpDFsdW7Wmq0%2B6UogTmg%3D%3D)![](https://students.senecapolytechnic.ca/attachment?file=pvTnZbYU0%2FSxg2vr1BDAiw%3D%3D)Trace Width: - Minimum: 18 mils. - Recommended: 30 mils. - Maximum: 180 mils. ![](https://students.senecapolytechnic.ca/attachment?file=6YNDXDjOtXOhAVCUeJP6ow%3D%3D) - Projects must meet the following drill bit guidelines: ![](https://students.senecapolytechnic.ca/attachment?file=Q6nwdnv%2BGqdTYamy81RkkQ%3D%3D) Drill holes that are smaller than 1.5 mm \(59.1 mils\) are rounded up to the closest drill bit size. Drill holes bigger than 1.5 mm are drilled to the specified diameter. Design guidelines per course: | Course | Board Outline \(mils\) | Layers | Other Requirements | | --- | --- | --- | --- | | CAD266 | 2000x2000 max | Single | | | CAD366 | 3000x3000 max | Single | 4 Mounting holes, 5.08mm screw terminals, 9-position D-Sub Plug | | COM455 | 2000x3000 max | Single | | | DGS266 | 3000x2000 max | Single | | | ECP455 - Assignment | 1500x1500 max | Single | | | ECP455 - Project | 3000x2000 max | Single | 4 Mounting holes, 5.08mm screw terminals | | ECR255 | 1000x1000 max | Single | | | ECR353 | 3000x2000 max | Single/Double | | | ELD255 | 3000x2000 max | Single | | | ETD555 | 3000x2000 max | Single/Double | | | HSI255 | 2000x2000 max | Single | | | HSI266 | 2000x2000 max | Single | | | HSI355 | 3000x2000 max | Single/Double | | | TPJ452 | N/A | Single/Double | 4 Mounting holes | | TPJ653 | N/A | Single/Double | 4 Mounting holes, 5.08mm Screw Terminal | | TPJ655 | N/A | Single/Double | 4 Mounting holes | | TRN553 | N/A | Double | Surface mount components only | | WCM555 | 3000x2000 max | Single/Double | | - Once the project is printed, the students will receive an email from the Seneca PCB Lab for pick up. PCB pick ups are available during the Open Lab session. Have your Seneca photo ID \(virtual Seneca OneCard\) ready for pick up. Students cannot pick up PCBs on behalf of someone else, except for your project partner, who must be disclosed on the email request. **Any questions about PCB design or Software must be discussed with your instructor. We cannot offer advice on PCB designs.** - Students can only print one project PCB at a time \(per course\). If they want to make a revised board, then the original board must be returned when picking up the revised board \(even if there are components soldered onto it\). - Only PCBs designed using Fusion are supported. Converted projects from other software applications are not accepted. - If the board file or any Manufacturing \(Gerber\) files are missing, the project will be returned to the student. - Every student project will be compared for cheating and plagiarism. If an issue is found, the students involved will undergo the Seneca [Academic Integrity Policy](https://www.senecacollege.ca/about/policies/academic-integrity-policy.html). - Projects are printed on a first come, first served basis. The lead time is 5 business days for Single-Sided projects and 7 business days for Double-Sided projects, starting from when the request is approved for manufacturing. - PCB Requests **will not** manufacture any designs submitted after the five business days leading up to the project’s due date. Please consult with your instructor and check the banner on the [Main Page](https://students.senecapolytechnic.ca/spaces/14/school-of-information-technology-administration-security/home) about the PCB Lab submission deadlines. ## Attachments - [padStack.png](https://students.senecapolytechnic.ca/attachment?file=6ibvxstKk11zYcpfkFttJg%253D%253D) - [clearanceNormal.png](https://students.senecapolytechnic.ca/attachment?file=PgCpDFsdW7Wmq0%252B6UogTmg%253D%253D) - [clearanceCopperPour.png](https://students.senecapolytechnic.ca/attachment?file=pvTnZbYU0%252FSxg2vr1BDAiw%253D%253D) - [traceWidths.png](https://students.senecapolytechnic.ca/attachment?file=6YNDXDjOtXOhAVCUeJP6ow%253D%253D) - [image_4049044331694201895583.png](https://students.senecapolytechnic.ca/attachment?file=Q6nwdnv%252BGqdTYamy81RkkQ%253D%253D) - [image_83683617421714054674460.png](https://students.senecapolytechnic.ca/attachment?file=jlPO9M6m6wCiJz%252FpUnjGEA%253D%253D) - [EMAIL.png](https://students.senecapolytechnic.ca/attachment?file=LJqdWtBnuAVoZEs1BmQSoQ%253D%253D) - [PCB Board Issue.png](https://students.senecapolytechnic.ca/attachment?file=2EgeOKGUHXahrTitaMmZUA%253D%253D) - [editimage0.png](https://students.senecapolytechnic.ca/attachment?file=%252BXXm6WolHWqluch%252ByPJ8IQ%253D%253D) - [PCB_Email.png](https://students.senecapolytechnic.ca/attachment?file=%252FF0J7lN4eB1zL2Zj%252BizqlA%253D%253D) - [SENECA POLYTECHNIC - PCB MANUFACTURING TIPS.pdf](https://students.senecapolytechnic.ca/attachment?file=Uo3ws7KhIOLMv40XqSC45g%253D%253D)
